Question

Draw the pattern of the arrangement of iron fillings around the bar magnet.​

Answer 1

Answer:

Answer

The diagram is as shown in the figure. The direction of the current is from M to N. The direction of the magnetic field created due to this current carrying loop is also shown. The direction of the magnetic field is got by using Right Hand Thumb Rule at each point of the loop considering the direction of the electric current. This rule states that:

Imagine that you are holding a current-carrying straight conductor in your right hand such that the thumb points towards the direction of current. Then your fingers will wrap around the conductor in the direction of the field lines of the magnetic field.

The iron filings will be arranged in the direction of the magnetic field as shown.
