Questions from William Heathcote Solutions for Chapter: Consequences, Exercise 3: Exercise 3 with Hints & Solutions
The diagram below shows an iron rod with two coils of wire around it. Coil X is connected to a battery and a switch; coil Y is connected to an ammeter. When the switch is closed, coil X acts like an electromagnet. Coil Y experiences a change in the magnetic field and has a current induced in it which causes the ammeter to jump to the right. The ammeter then returns to zero
Explain why the ammeter registers a current when the switch is first closed, but after a short time, the current reading returns to zero.

When the switch is closed, coil X acts like an electromagnet. Coil Y experiences a change in the magnetic field and has a current induced in it which causes the ammeter to jump to the right. The ammeter then returns to zero
Describe the reading on the ammeter when the switch is opened again.

When the switch is closed, coil X acts like an electromagnet. Coil Y experiences a change in the magnetic field and has a current induced in it which causes the ammeter to jump to the right. The ammeter then returns to zero
The number of turns in the wire in coil X is doubled. Explain why the ammeter reading is greater when the switch is closed.
