Question

Mrs. Brown's class is studying magnets and electricity. At the end of the unit Claire states that magnets and electricity are both non-contact forces like gravity, but they are not related other than that. Sammy says that magnets and electricity are closely related, but isn't sure how. If you were Mrs. Brown, how would you explain the relationship between magnets and electricity to the class? Check all that apply.
Question 7 options:

Magnets can create electricity and electricity can create a magnetic force.


Both electric charges and magnets do not have to touch an object in order to exert a force on it.


Electromagnets use electricity to create a magnetic force.


Generators convert electrical energy into magnetic energy.

Answer 1

Answer:

Magnets can create electricity and electricity can create a magnetic force.

Both electric charges and magnets do not have to touch an object in order to exert a force on it.

Electromagnets use electricity to create a magnetic force.

Explanation:

Answer 2

Answer:

The correct options are

1. Magnets can create electricity and electricity can create a magnetic force.

 

2. Both electric charges and magnets do not have to touch an object in order to exert a force on it.

3. Electromagnets use electricity to create a magnetic force.

Explanation:

1. As magnetic flux linked with a coil changes an induced current is developed. This is called electromagnetic induction.

A current carrying conductor always produces magnetic field near the conductor. This is called magnetic effects of current.

2. Electric force and the magnetic force both are the non contact force.

3. Electromagnet works only when electric current pass through the coil.
