# Can magnetic fields be combined?

## Can magnetic fields be combined?

When magnets are close together, with their fields overlapping, the fields combine to produce a resultant field which acts in one direction at any given point. The forces due to both magnets cancel each other, i.e. there is no net force, at X.

Can you have a magnetic field without an electric field?

No you can have a magnetic field without an electric field. Consider a rod with an equal number of positive and negative charges (such that they are equally spaced). Let the positive move to the left with speed v and the negative to the right with speed v. This will result in a magnetic field but no electric field.

### Can magnetic fields cancel each other out?

Magnetic fields can cancel each other out. This is owed to the factor that magnetic fields are vector quantities. If the magnitude of two fields is equal, but the pull is in opposite directions, the net result is that the magnetic fields will cancel out.

What happens when 2 magnetic fields interact with each other?

When opposite ends of two magnets interact, their field lines connect the north pole of one with the south pole of another, and the two attract. When the same ends of two magnets interact, they repel because the lines cannot cross and are compressed by each other.

## Does a magnetic field really exist?

However, purely magnetic fields do exist. Therefore, magnetic fields are more than just relativistic electric fields. The correct statement is that electric fields and magnetic fields are both fundamental, both are real, and both are part of one unified entity: the electromagnetic field.

Do all electric fields have magnetic fields?

Electric fields are generated around particles that bear electric charge. Positive charges are drawn towards it, while negative charges are repelled. A moving charge always has both a magnetic and an electric field, and that’s precisely the reason why they are associated with each other.

### What happens when 2 magnetic fields collide?

American space scientists show what happens when two magnetic fields collide. “Our data clearly show that electrons suddenly cease to follow magnetic fields and zoom off in another direction, corkscrewing and turning.

How does two magnetic fields interact?

When opposite ends of two magnets interact, their field lines connect the north pole of one with the south pole of another, and the two attract. When the same ends of two magnets interact, they repel because the lines cannot cross and are compressed by each other. Now, magnetic materials have two poles.
