Question

1. A bar magnet is equivalent to
+​

Answer 1

Answer:

Both a bar magnet and current carrying solenoid produce similar magnetic lines of force around them in closed loop. Hence, bar magnet can be modeled equivalent to a solenoid.

Explanation:

ok bro ........... it's your answer

Answer 2

Answer: hey mate,

solenoid carrying current

Explanation:

When a bar magnet is cut into two halves, both the pieces act as a magnet with the same magnetic properties whereas when a solenoid is cut into two halves, they will have weaker fields. The poles of the bar magnet are fixed whereas for a solenoid the poles can be altered.

Similarities between a Bar Magnet and a Solenoid

Bar magnet and solenoid both have attractive and directive properties ie, to align itself along the external magnetic field.

The magnetic field at the axial point is the same for both.

The magnetic moment is the same for both.
