Answers
Answer:
a magnetic field is a vector field which is in close proximity to a magnet and a circuit with current passing through it.
a magnetic field is produced by the movement of electric charges.
James clerk Maxwell announced many theories on electricity and magnetism, these by popularly known as maxwell's equations. They described the relationship between electricity and magnetism.
magnetic field is region around a magnetic material or a moving charge within which the force of magnetism acts.
Symbol = B or H
Unit = Tesla
Base unit = Coulomb
a magnetic field can be illustrated in two ways. oneness through magnetic field vector and the other is true magnetic field lines.
Answer:
A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field.
Magnetic fields can be pictorially represented by magnetic field lines, the properties of which are as follows:
- The field is tangent to the magnetic field line.
- Field strength is proportional to the line density.
- Field lines cannot cross.
- Field lines are continuous loops.
