Question 36
What happens when a magnet is moved towards a solenoid?
A current is induced in the solenoid that opposes the
movement of the magnet, according to Lenz’s law.
The right-hand rule can be used to determine which
direction the current must flow to oppose the magnet’s
motion.
If the magnet’s north-pole is moving forwards towards the
magnet from our point of view, then the current through the
solenoid will flow anticlockwise.

Question 37
(a) Describe the amplitude of the varying magnetic field
produced by a sinusoidally varying electric current.
The magnetic field produced will vary in the same way, i.e. it
will also be sinusoidal. ↙
(b) Describe the amplitude of the varying electric current
produced by a sinusoidally varying magnetic field.
The electric current produced will have amplitude
proportional to the sinusoidally varying flux, so it will also be
sinusoidal. ↙

Question 38
Outline how electricity and magnetism are related.
Electric currents can create magnetic fields, and magnetic
fields can create electric currents.
An electric current through a straight wire creates a circular
magnetic field around the wire; a current-carrying solenoid
produces a magnetic field like a bar magnet.
A changing magnetic field produces an electric current that
has strength proportional to the rate of change of the
field. ↙

Question 39
Describe the operation of a transformer.
A transformer consists of a primary coil of wire and a
secondary coil of wire, often both wrapped around a
laminated iron core.
When an alternating electric current flows through the
primary coil, a changing magnetic field is induced (in the iron
core, if present).
The changing magnetic field produces an alternating electric
current in the secondary coil, with a voltage proportional to
the number of turns in the coil.

Question 40
Describe how Thomas Edison tried to promote the use of DC
electricity over AC electricity.
Edison pushed his own DC electricity scheme forward by
trying to convince the public that the AC electricity of
Westinghouse and Tesla was too dangerous to be used.
To prove his point, he tortured and killed animals with AC
electricity, and even had an electric chair constructed to
execute condemned criminals.
His campaign did not succeed, and now AC electricity is
universally used for electricity generation and
transmission.
