Question

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

A. 16 units
B. 32 units
C. 128 units
D. 256 units

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

A. 1.5 units
B. 0.75 units
C. 24 units
D. 10.6 units

Answer 1

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.

Answer 2

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.
