Simulation with the bar magnet

Category: Engineering Paper Type: Report Writing Reference: APA Words: 1700

For the simulation, we have selected the pet link and then from this link according to the instruction is given in that link pick the physics subject that is provided at the left side of the page and then from this subject chooses the topic of magnets and electromagnet.

In the simulation page, we can see that there is a bar magnet and this magnet has two poles that are the North Pole, and the other one is the South Pole. The electric line of forces transferred from the North Pole to the south pole of this bar magnet. It can be seen that when two south magnet collides and the two north poles collide the repulsion process occurs. The north pole of the bar magnet is attracted towards the south pole of the attraction. The magnetic field of the appeal is not the same at every point it is unique at every position. These magnetic lines of the bar magnet are continues and unbroken, and these magnetic lines of the attraction form a closed loop. These lines of forces start from the north pole of the magnet, and these lines are terminated on the south pole of the appeal.

While experimenting it is observed that when the bar magnet is moved in the right direction the needle of the compass also move toward the right direction which indicates that the compass always moves toward the position of the magnet. The red portion of the compass needle still depicts the north, and the white part of the needle depicts the south direction. In the past, the compass was used for finding the path. The world's electric, magnetic field moves the compass and individuals can see the direction.  In the experiment, the same phenomenon can be observed.

The magnetic field depends on the strength of the bar magnet. Form the simulation it can be seen that the magnetic field is too much low because the power of this magnet is set up to 10% only. As the strength of this magnet is increased by changing the value of the attraction, it can be seen that the magnetic field of this magnet increases. It can be understood that when you set the strength of this magnet at the 0 % there is no magnetic field exists for this magnet. 

If we click on the see inside a magnet, it can be seen that the magnetic lines of this magnet migrate from the north pole of the attraction to the south pole of this magnet. Then after this, you have to select the compass from the options of the bar magnet. It can be seen that the compass north magnet is according to the north magnet of the attraction. In this condition, the bar magnet is in front of the compass that has been selected. If the position of the bar magnet changes like upward and downward so it can be seen that there is no effect on the compass. The location of the bar magnet changes from downward to upward when the magnet moves downward the direction of the compass changes the needle and it points towards downward and after this when you run the attraction in the upward trend the needle of the compass again changed. Then after this, the bar magnet is moved towards the compass, and it can be seen that the needle of the compass shifts still but in this case the direction is different. The north needle is opposite to the north pole of the magnet. Then after this, the position of this magnet is again changed, now, in this case, the needle of the compass again shifted and far back the syringe of this compass is shifted again.

From this phenomenon, it can be seen that the needle of the compass is always pointed towards the north pole of the magnet. The syringe of this magnet is still towards the north pole of the attraction.

Now this phenomenon can be seen by decreasing the strength of the magnet. The power of the attraction is set up to 25%.  It can be understood that there is minimal deflection seen by the needle of the compass. Then after this move the position of the magnet downward but there is still very low deflection can be seen from the needle of the compass. Then after this in the next case put the magnet near the compass so the deviation can be observed from the needle of the compass.

Now in the next step select the field meter for this, there are four parameters when you select the field meter.  After this flip the polarity of the bar magnet. It can be seen that all the values form the field meter reading changes with the sign of negative except the value of the magnitude of bar magnet magnetic field.

After setting the strength of the bar magnet to 0% no deflection can be seen and also there is no magnetic line of forces. Then after this setting the power of the bar magnet at 10 %, it can be seen that there is shallow deflection form the needle of the compass. The magnitude of the magnetic field can be seen that is 0.01. Afterward when the position of the magnet changes again and put the magnet exceptionally far from the magnetic field meter. There is no value on the x-axis, and also no value on the y-axis can be seen.

After this increase, the strength value of the bar magnet up to 20% but the position of the attraction is the same in that case. It can be seen that from the simulation the value of the magnitude of the magnetic field is changed up to 0.01 and the amount of this is come from adding the x-axis magnetic field and y-axis magnetic field. In this case, the value of the x-axis is 0.01, and the amount of y-axis is 0, so the magnitude of the magnetic of the magnetic field is equal to 0.01. The value of the orientation of the magnetic field is 7.97. Now again change the strength of the bar magnet, the power of the bar magnet is set up to 30%.

There is no difference can be seen on the field meter that is used in this simulation, the reason is that the strength of the bar magnet is still low. Then in the next step again change the power of the bar magnet up to 40% at that stage it can be observed that there is still no change in the reading of the field meter. The field meter even shows the same value. Then again change the strength value of the bar magnet up to 50%. When the strength of the magnet varies to that point so the value of the x-axis has been changed, and it becomes 0.02 but there is still zero value of the y-axis, so according to that the value of the magnitude of the magnetic field will be changed up to 0.02, and the orientation value of the magnet is still the same. Then in the next step change the strength value of the bar magnet up to 60%.

 By changing the value of the strength, the magnetic field x-axis value will be changed up to 0.03, but there is still no change in the y-axis because there is no change in the position. The magnitude of the magnetic field will be 0.03, and also there is no change in the orientation angle of the magnetic felid. Then in the next step again change the strength of the bar magnet and set the value of resistance of bar magnet up to 70%. It can be seen that there is no change in the cost of the magnetic field meter the price is still the same as for the 60% magnetic strength. Now again change the amount of the magnetic power up to 80%, and it can be seen that the value of the x-axis of the magnetic field will vary from 0.03 to 0.04 and there is also deflection in the y-axis. It can be observed from the simulation that is only 0.01, but the value of the magnitude is still set at 0.04, and there is no change in the orientation can be seen. Then after this again change the strength of the bar magnet up to 90%, and it can be seen that there is still no deflection can be seen. Now set the value of the strength of bar attraction up to 100%. From the simulation, it can be seen that the x-axis value of the magnetic field will be shifted at 0.05 and the y-axis value is still the same.

From the above phenomenon, it can be seen that as the strength of the magnet increases so that according to that there is a deflection in the magnetic field can be observed. The magnetic field depends upon the power of the attraction and also the distance of the bar magnet. As the length of the bar, a magnet is increased, so there is a decrease in the strength of the magnetic field. The magnetic field will be low when the range is increased. The power of the bar magnet is directly proportional to the magnetic field, as the power of the attraction is high, so it means that the value of the magnetic field will be high too. And if the strength of the appeal is low, so the cost of the magnetic field is also low. This phenomenon can be seen from the observation.

Now in the next step select the option from the bar magnet option, the choice of planet earth. It can be seen that the earth planet has two poles like the bar magnet. The one is the North Pole, and the other one is the South Pole, and it can be observed the deflection needle of the compass is opposite to the poles of the earth.
