PS Unit 7 L4.2 - Analyzing Current and Magnetic Field

Front

What is electromagnetism?

Back

Electromagnetism is the branch of physics that deals with the relationship between electricity and magnetism.

Front

How can electricity be generated using electromagnetism?

Back

Electricity can be generated by moving a magnet through a coil of wire.

Front

What is a solenoid?

Back

A solenoid is a long coil of wire that creates a magnetic field when an electric current passes through it.

Front

What happens to the magnetic field when the electric current in a wire stops?

Back

The magnetic field would disappear.

Front

Why do solenoids produce stronger magnetic fields in a smaller space?

Back

Because the magnetic fields of different parts overlap and combine.

Front

What is the core of a solenoid?

Back

The core of a solenoid is the object around which the wire is wrapped.

Front

What is the relationship between electric current and magnetic fields?

Back

Electric current creates a magnetic field around the wire.

Front

What is the effect of increasing the number of coils in a solenoid?

Back

Increasing the number of coils strengthens the magnetic field produced.

Front

What materials are commonly used as cores in solenoids?

Back

Iron is commonly used as a core material in solenoids to enhance the magnetic field.

Front

What is the direction of the magnetic field around a current-carrying wire?

Back

The direction of the magnetic field can be determined using the right-hand rule.
