Physics Moving Charge and Magnetism Matching Type Question MCQ (Single Correct)

Match the figure in Column I with their magnitude of magnetic field at point O in Column II.

Choose the correct answer from the options given below.

A-III, B-IV, C-II, D-I

A-III, B-IV, C-I, D-II

A-I, B-II, C-III, D-IV

A-II, B-I, C-III, D-IV

Verified by Experts

The correct answer is:

Magnetic field at O due to straight wires is zero

B 1 and B 2 both directed outward
Magnetic field at the center point O,

Magnetic field at O due to straight wire,

B 1 is directed inward and B 2 is directed outward.

Magnetic field at the center O,

Magnetic field, , (outward)
Magnetic field, , (outward)
Magnetic field,
Magnetic field at the center,

From the figure,

Magnetic field at the center O,

Hence, A-III, B-IV, C-II, D-I.
