Question

character feature of magnetic field​

Answer 1

Feautre of magnetic force are as follows:-

• 1. Magnetic force of do not intersect each other.

• 2. These forces act only on moving charges and not on the particles at rest (velocity dependent).

• 3. If the magnetic force moves along the direction of the magnetic field then no magnetics force acts as a charge.

• 4. It depends on force (F), charge (q), velocity (v) and the strength of the the magnetic field (B).The formula for the magnetic force (F) = q × v × B.

• 5. The magnetic forces (F) = IlB where I is the current, l is the length of magnetic filed and B is the magnetic field.

The properties of magnetic field lines can be summarized by these rules: The direction of the magnetic field is tangent to the field line at any point in space. A small compass will point in the direction of the field line. The strength of the field is proportional to the closeness of the lines.

Characteristics of magnetic field lines: The lines originate from the north pole and terminate on the south pole of the bas magnet. The strength of the magnetic field is proportional to the density of lines. Magnetic field lines cannot cross each other.
