8(a)Magnetic Fields CurrentsEasy3 marks

A teacher uses the arrangement shown in Figure 8.1 to demonstrate how an intruder alarm works.

Figure 8.1, an intruder alarm demonstration: a coil of wire wound on a soft-iron bar held by a clamp and stand is connected through switch S to a battery, and below it a pivoted soft-iron arm mounted on an insulator carries contacts wired into a bell circuit

Switch S is connected to a door. When the door is open, switch S is open. When the door is closed, switch S is closed.

Complete the sentences to explain how the arrangement can be used as an intruder alarm.

The teacher closes the door and the battery produces a in the coil of wire. The soft-iron bar is and attracts the soft-iron arm. When the door is opened, the contacts touch and this the bell circuit, causing the bell to ring.

8(b)(i)Transformers Power TransmissionEasy2 marks

Figure 8.2 shows a transformer that is 100% efficient.

Figure 8.2, a transformer with a primary coil of 360 turns connected to a 240 V a.c. supply and a secondary coil of 40 turns, both wound on a core

Calculate the voltage

V_{s}

across the secondary coil.

8(b)(ii)Transformers Power TransmissionEasy2 marks

A student connects the primary coil of the transformer to a d.c. supply. Explain why there is no voltage across the secondary coil.
