You asked: What you mean by electric field lines and magnetic field lines?

It is exactly proportional to the number of lines per unit area perpendicular to the lines (called the areal density). Magnetic field lines can never cross, meaning that the field is unique at any point in space. Magnetic field lines are continuous, forming closed loops without beginning or end.

What is the difference between electric field lines and magnetic field lines?

The electric field is defined by straight field lines. They do not form closed loops. Magnetic field lines form a closed loop starting from the north pole and terminating at the south pole outside the magnet.

What is magnetic field line?

Magnetic field lines: Magnetic field lines are imaginary lines around the magnet. The magnitude of a field is indicated by its line’s density. Near to South and North Pole of a magnet, the magnetic field is stronger and will get weaker when it moves away from the poles.

What are the similarities and differences between electric and magnetic fields?

Similarities between magnetic fields and electric fields: Electric fields are produced by two kinds of charges, positive and negative. Magnetic fields are associated with two magnetic poles, north and south, although they are also produced by charges (but moving charges). Like poles repel; unlike poles attract.

GOOD TO KNOW:  Your question: What happen if electrical generator run without load?

What is the symbol of magnetic field?

Index to magnetic terms & units in the SI

Quantity name Quantity symbol Quantity symbol
magnetic field strength H Φ
magnetic flux density B χρ
magnetic moment m J
magnetic susceptibility χ M

Why is electric field stronger than magnetic field?

An electromagnetic field (also EM field) is a classical (i.e. non-quantum) field produced by accelerating electric charges. … The force created by the electric field is much stronger than the force created by the magnetic field.

What causes a magnetic field?

Magnetism is caused by the motion of electric charges. Every substance is made up of tiny units called atoms. Each atom has electrons, particles that carry electric charges. … Their movement generates an electric current and causes each electron to act like a microscopic magnet.
