Magnetic force is a physical interaction between two objects that occur through the power of magnetism. Magnetic force can be used to move objects, create electricity, and store data. The strength of the magnetic force between two objects depends on the distance between them.

Magnetic field: A region in which a magnetic force is exerted on any magnetic material, such as iron, nickel, or cobalt. Magnetic Force: The force of attraction or repulsion between two magnets or between a magnet and a magnetic material. Magnetic Flux: The number of lines of force passing through a given area perpendicular to the direction of the lines of force.

Applying a magnetic force can cause an object to rotate even if the object is not exposed to a physical force. When a magnetic field is applied to an object, the object can actually take on the properties of the field and become magnetized itself. It is possible to use a magnetic field to levitate objects in mid-air.

What happens when you apply a magnetic force on a non-magnetic object?
• Nothing happens
• The object may experience induced electric current and generate its own magnetic field
• The object will become temporarily magnetized
