Why is there a magnetic field around a magnet?

The magnetic field is the area around a magnet that has magnetic force. All magnets have north and south poles. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field.

Why do magnetic fields form?

When an electric charge moves it generates a magnetic field. When an electric current flows it generates a magnetic field because an electric current is moving charges. Electromagnets are made from strong electric currents flowing through a coil of wire.

Why do magnetic field lines point from north to south?

When it comes to magnets, opposites attract. This fact means that the north end of a magnet in a compass is attracted to the south magnetic pole, which lies close to the geographic north pole. The geographic north and south poles indicate the points where the earth’s rotation axis intercepts earth’s surface.

Why are magnetic fields stronger closer to the magnet?

the magnetic field lines never cross each other. the closer the lines, the stronger the magnetic field (so the magnetic field from a bar magnet is strongest closest to the poles)

What will happen if magnetic field lines intersect?

A tangent drawn on a magnetic field line gives the direction of the magnetic field at that point. The magnetic field lines never intersect each other because if two or more lines intersect each other than it means that at that point of intersection, the magnetic field has two directions at the same point.

Where is the magnetic field around a magnet the strongest?

poles
the magnetic field lines never cross each other. the closer the lines, the stronger the magnetic field (so the magnetic field from a bar magnet is strongest closest to the poles)

What does it mean if the magnetic field lines are closer together?

The closer together the field lines, the stronger the magnetic field. The more spread out they are, the weaker the magnetic field.
