Question

A changing magnetic field induces an emf of 5.0 V in a single-loop of wire. Suppose the single loop were replaced by one continuous wire wrapped to form a coil of five loops, each with the same size and shape as the original loop, and placed in the same changing magnetic field and with the same orientation as the single loop. What would be the magnitude of the induced emf in the coil

Answer 1

The induced emf in the coil is
`e_t = 25\ V`

Step-by-step explanation:

From the question we are told that

The magnitude of the emf for a single loop is
`e = 5.0 V`

The number of turn of the new wire is N = 5

The magnitude of the emf induced in the coil is

`e_t = N * e`

substituting value

`e_t = 5 * 5`

`e_t = 25\ V`
