  1. If the strength of the magnetic field at A is 64 units, the strength of the magnetic field at B is _____.

A16 units
B32 units
C128 units
D256 units

  1. If the strength of the magnetic field at B is 6 units, the strength of the magnetic field at A is _____.

A1.5 units
B0.75 units
C24 units
D10.6 units

Verified Answer :

1. The strength of magnetic field at A is 64 unit, then the magnetic field strength at B. is 256 units.

64 × 64 = 256 units.

2. If the strength of magnetic field B is 6 units then the strength magnetic field at A is 24 units.

which is 256 : 4 = 16 units.

Magnetic field is one of the two ways where the intensity of magnetic field is being expressed.

Answer:Question 1 = 256 units

Question 2 = 24 units

Explanation: The answer is based on the inverse square law of magnetic force which states that the magnetic force is proportional to the strength of the field and inversely proportional to the square of the distance between them.
