Question 21

An electronic microbalance utilizes a straight segment of gold wire, of active length 45.0 mm, suspended at right angles to a uniform magnetic field.

When a current of 1.60 A passes through the wire, the magnetic force exerted on it is 2.88 × 10-2 N.

Calculate the magnetic flux density of the magnetic field.

Use the equation:

F=B×I×l F = B \times I \times l F=B×I×l
