Electromagnetic effects — practice question

A student carries out an investigation into electromagnetic induction. Fig. 10.1 illustrates the setup she is using.
(a(i))[2]

The meter shows both the magnitude and the direction of the induced electromotive force (e.m.f.). On Fig. 10.2, sketch the pointer position on the meter for each stage. One example has already been completed for you.

(a(ii))[2]

Describe how the student could make the induced electromotive force (e.m.f.) larger.

(b)[3]

Calculate the output voltage.

(c)[2]

State two advantages of high-voltage transmission of electrical energy.
