What three minerals are attracted to a magnet?

CHECK ALL THAT APPLY.

1

What is it about these minerals that make the Earth one big magnet?

1

Magnetism is made up of moving electrons. Where do these moving electrons come from when making an electromagnet?

1

What is it that makes a magnet different from a piece of iron that is not magnetic?

1

What makes magnetic objects different from non-magnetic objects?

1

Just like the N and S poles on bar magnets, electrons and protons _______ each other.

1

When an electric current flows through a wire, a magnetic field is created. To increase the power of the magnetic field, _______ .

Electromagnetic conduction involves creating an electric current using magnets and a coil of wire.

Watch this video titled "Electromagnetic Induction - 3D Animation."

What is created when North and South magnetic poles are placed close to each other?

1

What do you think the blue circles going around the wire represent?

0

Do you think you would get the same outcome if you put the two North poles together? Explain.

Explore magnets by dragging objects to the line and clicking play. Observe what happens with the magnets and different objects.

Next, click on the tab that says, "Magnetic Field Lines." Drag an object or objects to the line, click "sprinkle fillings", then "tap table." What do you observe?

Put the items into the TRUE or FALSE category.

  • The coils in an electromagnet make very little impact on the strength of the magnetic force..
  • The north poles of two different magnets will attract each other.
  • Magnets are found naturally in the Earth.
  • Magnetic forces can be seen with the naked eye.
  • Increasing the number of coils in an electromagnet will increase the power of the magnet.
  • Most magnets are made from 100% aluminum
  • Iron, nickel, and cobalt can all be made to be magnetic
  • Opposite poles of magnets attract, and similar poles repel each other.
