Magnetic Power Of Different Magnets

Experiments | 7-11 yrs | Video

REQUIREMENTS

  • Bar magnet
  • Horseshoe magnet
  • Circular magnet
  • Ruler
  • Safety pins

WHAT TO DO

Place the coins against the ruler about 10 cms apart. Similarly, do the same for the magnets. Using the ruler, gradually push the safety pins closer to the magnets.

WHAT HAPPENS

Some of the safety pins are attracted by the magnets almost at once, others only when they are a short distance away.

WHY THIS HAPPENS

Magnets can exert their force at a distance from things.The larger the magnet, the stronger its force and greater the distance at which it can attract objects.
