Answer: C) an electric current

Explanation:

Changing magnetic field induces electromotive force which results in electric current to flow in conducting wire.

<u>From Faraday's Law:</u>

induced emf,

e = -N \frac{\Delta B A}{\Delta A}

Thus, when magnet is quickly turned, a change in magnetic field would produce an electric current.

<h2>Answer:</h2>

<u>Turning a magnet very quickly would be BEST used to create an electric current</u>

<h2>Explanation:</h2>

In Electromagnetic waves electric field produces magnetic field and vice versa. A moving magnet can produce electric current. Dynamo is the best example for it. In dynamo armature is rotated between the magnets which results in the development of electric field and hence an electric current is produced in it.

Which of the following is a sample of igneous rock?
Blizzard [7]

Answer:

I would say it's B. But just in case here is some information if I'm wrong.

Explanation:

Igneous rocks are very dense and hard. They may have a glassy apprearance. Metamorphic rocks may also have a glassy appearance. You can distinguish these from igneous rocks based on the fact that metamorphic rocks tend to be brittle, lightweight, and an opaque black color.
