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) Magnetic force on a straight conductor | (i) F = I l × B |
| (b) Direction of magnetic field lines | (ii) Right-hand rule |
| (c) Force on a moving charge | (iii) q(v × B) |
| (d) Current carrying wire in a magnetic field | (iv) Circular motion of charge |
A
a-i, b-ii, c-iii, d-iv
B
a-ii, b-iv, c-i, d-iii
C
a-iii, b-i, c-ii, d-iv
D
a-iv, b-iii, c-ii, d-i
Correct Answer
Option A
Detailed Explanation
The magnetic force on a straight conductor carrying a current is given by F = I l × B, where the direction is determined by the right-hand rule. The force on a moving charge is expressed as q(v × B). These relationships are directly referenced in the context of magnetic forces on current.
