INVESTIGATION 2 I-CHECK ELECTROMAGNETIC FORCE

Front

What is an electromagnet?

Back

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. It can be turned on and off.

Front

What is magnetic force?

Back

Magnetic force is the attraction or repulsion that arises between electrically charged particles due to their motion.

Front

What materials are attracted to magnets?

Back

Materials that are attracted to magnets include iron, nickel, and cobalt.

Front

What is a magnetic field?

Back

A magnetic field is an invisible area around a magnet where magnetic forces can be felt.

Front

What happens when two magnets are brought close together?

Back

Two magnets can either attract or repel each other depending on their poles: like poles repel, while opposite poles attract.

Front

What is the role of iron filings in demonstrating magnetic fields?

Back

Iron filings can visually show the pattern of a magnetic field when sprinkled around a magnet.

Front

What is the difference between permanent magnets and temporary magnets?

Back

Permanent magnets maintain their magnetism over time, while temporary magnets only exhibit magnetic properties when in a magnetic field.

Front

How does the strength of a magnet change with distance?

Back

The strength of a magnet's force decreases as the distance from the magnet increases.

Front

What is the significance of the poles of a magnet?

Back

Every magnet has a north and south pole; the north pole of one magnet will attract the south pole of another magnet.

Front

What is the effect of temperature on magnetism?

Back

Increasing temperature can demagnetize a magnet, as heat can disrupt the alignment of magnetic domains.
