Physics-Magnetic Force on Current
NEET Physics Magnetic Force on Current Match the Following Question
Type: Match the Following-match the column-Easy-Class 12
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Current in the same direction | (i) Attracts each other |
| (b) Current in opposite direction | (ii) Repels each other |
| (c) Force on a wire in a magnetic field | (iii) Given by F = I B L sinθ |
| (d) Magnetic field due to a long wire | (iv) Circular pattern around the wire |
A
a-i, b-ii, c-iii, d-iv
B
a-ii, b-i, c-iv, d-iii
C
a-ii, b-iii, c-i, d-iv
D
a-i, b-iii, c-iv, d-ii
Correct Answer
Option A
Detailed Explanation
In the context of magnetic forces, currents flowing in the same direction attract each other, while those in opposite directions repel. The force on a wire in a magnetic field is indeed given by F = I B L sinθ, and the magnetic field due to a long wire circulates around the wire.
