Electric and Magnetic Fields Quiz

What is the difference between a magnetic field and an electric field?

• The difference between a magnetic field and an electric field is that a magnetic field is created by moving electric charges or by magnetic materials, while an electric field is created by stationary electric charges.

• A magnetic field is created by stationary electric charges, while an electric field is created by moving electric charges or by magnetic materials.

• A magnetic field is created by gravity, while an electric field is created by electromagnetic radiation.

• A magnetic field and an electric field are the same thing.

1. Describe the concept of electric field lines and how they represent the strength and direction of an electric field.

• Electric field lines are physical lines that can be seen in an electric field.
• Electric field lines only represent the strength of an electric field, not the direction.
• Electric field lines are only applicable to magnetic fields, not electric fields.
• Electric field lines are imaginary lines that represent the direction and strength of an electric field.
