Determine factors that affect electric and electromagnetic forces - Middle School Physical Science

The answer is "They repel."

Magnetism is the force by which objects are attracted to or repelled by other objects. Magnets have two opposite ends, called poles. The north pole of one magnet will repel, or push away, the north pole of another magnet. The same thing will happen with two south poles. North and south poles of magnets are attracted to each other.

Magnetism involves electrons and electricity. Most iron is not permanently magnetic, but it can be made into a temporary magnet. The reason this is possible has to do with the electrons that make up the iron atoms. When the electrons are lined up just right, the piece of iron becomes a temporary magnet.

We call permanent iron magnets “Ferromagnetic,” but electricity is often used to make a type of magnet, called an electromagnet. Electromagnets are made from copper wire coiled around a core. Iron placed inside the core makes the magnet stronger. When an electric current is sent through the coiled wire, the wire becomes magnetized. When the current stops, the magnetism stops too.

The answer is "a copper wire, a nail, and a battery." The battery provides electricity which travels through the copper wire, and changes the alignment of the electrons in the iron nail, making it magnetic.

The answer is decreases. Magnetism is more powerful when objects are closer together.

The answer is all of these. Iron, nickel, and cobalt are the three types of magnetic metals.

The answer is "all of these affect the strength of a magnet" The proximity to the object, the size of the object, the material of the object it is sticking to, and the temperature of the object all affect magnetic pull.

The answer is, the one with more loops. Having more loops around the core will increase a magnet's strength.

The answer is "the magnetic field." The magnetic field shows us the influence of electrical charges around magnets.

The answer is "the core is made of iron" because the image shows an electromagnet. Electromagnets need an iron core, magnets, and a copper wire to function.
