Question

A loop of wire carries a current. The resulting magnetic field __________.a. points toward the loop at all pointsb. points away from the loop at all pointsc. is similar to that of a bar magnet in the plane of the loopd. is similar to that of a bar magnet perpendicular to the plane of the loop

Answer 1

d-similar to that of a bar magnet perpendicular to the plane of the loop

Step-by-step explanation:

Current is rate of flow of charge. Magnetic field due to a current carrying wire depends on the current in the wire and the distance of the point from the wire. The direction of the magnetic field is perpendicular to the wire. This is demonstrated in Flemming's Right hand rule

Answer 2

A loop of wire carrying a current will have a magnetic field similar to that of a bar magnet perpendicular to the plane of the loop.

What is Fleming's right hand rule?

This talks about the behavior of conductors in which directions of the magnetic field, the induced current, and the motion of the conductor are depicted by the first finger, second finger, and thumb of the right hand respectively when they are perpendicular to each other.

The above explanations thereby makes the option D the most appropriate choice.
