Description: a circular wire loop of radius r 12 cm is immersed in uniform magnetic field b 050t with its plane normal to the direction of the field if the field magnitude then decreased at a constant ra 16687

Step 1: The induced emf within the loop is given by Faraday's Law of electromagnetic induction,

Question

A circular wire loop of radius r = 12 cm is immersed in a uniform magnetic field B = 0.50 T with its plane normal to the direction of the field. If the field magnitude then decreases at a constant rate of 0.02 T/s, at what rate should the radius increase so that the induced emf within the loop is zero? Show full work. Caution: Both B and r are changing.

Step 1

The magnetic flux through the loop is given by the product of the magnetic field strength (B), the area of the loop (πr^2), and the cosine of the angle between the magnetic field and the normal to the loop (which is 0 degrees in this case). Show more…
