Please answer the following question: Answer the following question given this paragraph: 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. Q: A magnet can exert force on objects without touching them, as long as they are within what? Choices: - audio field - molecular field - gravitational field - magnetic field A:
Answer:
magnetic field
