Are permanent magnets only attracted to other permanent magnets?
No, they are attracted to: Other permanent magnets Solenoids Iron Wires with current running through them
Which magnet made by an electric current flowing through wires?
Electromagnet.
Two parallel wires carry electric current in opposite directions the magnetic forces of the two wires are?
Repulsive
When does electric current behave like a magnet?
An electric current is always surrounded by a magnetic field. This is more noticeable (for example, it can be detected with a compass) in the case of DC, and if the two wires of a circuit are separate.
Do toasters work because of the heating effect of an electric current?
Yes. resistance in wires within the toaster causes those wires to become very hot.
A break in the wires of an electric current will the circuit and the current?
A break in the wires of an electric current will break or cut the circuit and stop the current from flowing.

In an electromagnet the wires get hot due to the flow of what?
Electric current
When wires are connected to the terminals of a battery. what causes electric current in the circuit?
The resistance of the load is what causes an electric current to flow in a circuit.

Does electricity flow through wires?
Electric current flows through wires, but to transmit electric power you need two wires with a voltage between them, connected to a power source.
Why electrical wires have plastic covering?
Electrical wires have plastic covering as when electric current flows through the copper wires and mistake we hold it so we may get an electric shock.

Are magnets used in airplanes?
There are magnets in every electric motor, like in the little overhead fans. Electricity plus magnetism makes motion. There are also magnets in all of the telephones, microphones and speakers. Also, to avoid having to route very thick cables all the way to the cockpit for switching on things that draw a lot of current, like the engine starters, they have magnetic switches called solenoids near the high current equipment that they control, and regular thin wires connect the solenoids to the switches in the cockpit that control them. And like every other electric motor, the engine starters have magnets, too.
What can connect all the components in a circuit so that an electric current can flow?
Wires
