Q: A magnet can exert force on objects without touching them, as long as they are within what?


Read this paragraph and choose the correct option from the provided answers:

A familiar example may help you understand the vibrating electric and magnetic fields that make up electromagnetic waves. Consider a bar magnet, like the one in the Figure below . The magnet exerts magnetic force over an area all around it. This area is called a magnetic field. The field lines in the diagram represent the direction and location of the magnetic force. Because of the field surrounding a magnet, it can exert force on objects without touching them. They just have to be within its magnetic field.

 Choices:

- audio field

- molecular field

- gravitational field

- magnetic field


A:
magnetic field
