Magnetic Forces/Magnetism

What would happen to the magnetic field of a magnet, if the strength of the magnet increased?

• The magnetic field would decrease and will not be able to attract objects from a distance.

• The magnetic field will increase and will be able to attract objects from farther away.

• There would be no change to the magnetic field.

• The magnetic field would break.
