1. Something that is magnetic has magnetic fields. The fields start at the North Pole and go around the magnet, and terminate at the south pole of the magnet. All magnetic substances have north and south poles.
2. An electric field is the area that surrounds an electric charge an magnetic field is the are of the force around the magnetic poles it is induced by emf.

1) The explanation of the meaning of a substance being magnetic has been explained below.

2) The relationship between electric and magnetic fields has been explained below.

1) Magnetism is defined as the force exerted by magnets when they attract or repel one another other. This means this is caused as a result of the motion of electrons.

      Now, every substance is made up of atoms and each of these atoms have electrons that carry electric charges.

     Now, if these electrons are unpaired, then the atoms are said to be paramagnetic which means that they attract magnets. Thus, the substance will be said to be magnetic.

2) The major difference between a magnetic field and an electric field is that a magnetic field is caused by the movement of electric charges while an electric field is caused by stationary charges.

     Thus, when current is applied to a magnetic field, it causes the magnetic field to be orientated in a direction perpendicular to the direction of the current flow.
