Answer:
A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetized materials. A charge that is moving in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field
Explanation:
General Properties of Magnetic Lines of Force
They seek the path of least resistance between opposite magnetic poles. ...
They never cross one another.
They all have the same strength.
Their density decreases (they spread out) when they move from an area of higher permeability to an area of lower permeability.
