Select all the ways the magnitude (strength) of a magnet can be increased. (select 3)

• Distance-Magnetic forces will increase if two magnets are closer to each other.

• Distance-Magnetic forces will increase if two magnets are farther away from each other.

• Type of material used to make the magnet

• Size-The larger the magnet, the stronger the magnetic force

• Size-The smaller the magnet, the stronger the magnetic force

Why did the iron filings arrange themselves in this manner? Select 2 answers

• The magnetic forces increased as the iron filings fell farther away from the magnet.

• The magnetic forces increased as the iron filings fell closer to the magnet.

• The iron filings arranged themselves in this manner due to the magnetic field of the magnet.

• The magnetic forces remained the same as the iron filings fell all around the magnet.
