What type of circuit is shown in the picture?

• Series circuit

• Parallel circuit

• Open circuit

The three basic components of a circuit are

• load, energy source, magnets

• wires, load, solenoid

• wires, load, energy source

• energy source, iron core, load

In a series circuit, if one device goes out, the other devices

• remain on

• go out

Describe one way you can make an electromagnet stronger.

• Reduce the size of the iron core

• Decrease the current

• Decrease the energy source

• Increase the number of loops in the wire
