## What is the formula of magnetic field?

B = μ 0 I 2 π r The magnetic field has direction as it is a vector quantity. For conventional current flowing through a straight wire, this can be found by the right-hand rule.

What is the formula for magnetic field strength?

The definition of H is H = B/μ − M, where B is the magnetic flux density, a measure of the actual magnetic field within a material considered as a concentration of magnetic field lines, or flux, per unit cross-sectional area; μ is the magnetic permeability; and M is the magnetization.

What is magnetic field PPT?

Magnetic field The force with which a magnetic poles of a magnet attracts or repels another magnetic pole of another magnet is called as Magnetic force . The space or region around a magnet within which magnetic force is exerted on other magnet is called magnetic field of the magnet .

### What is the formula of magnetic field class 12th?

(i) In magnetic field F=q(V x B)

What is the SI unit of magnetic field?

Magnetic field is denoted by B and H. The SI unit of H is amperes per metre and the SI unit of B is Newtons per metre per ampere or Teslas.

What is SI unit of magnetic field?

#### What is the formula of tesla?

The tesla (symbolized T) is the standard unit of magnetic flux density. It is equivalent to one weber per meter squared (1 Wb · m -2 ). Reduced to base units in the International System of Units ( SI ), 1 T represents one kilogram per second squared per ampere (kg · s -2 · A -1 ).

What is magnetic field line Class 10?

Magnetic field lines are imaginary lines, which depict the strength and direction of the magnetic field.

What is meant by 1 gauss?

One gauss corresponds to the magnetic flux density that will induce an electromotive force of one abvolt (10-8 volt) in each linear centimetre of a wire moving laterally at one centimetre per second at right angles to a magnetic flux. One gauss corresponds to 10-4 tesla (T), the International System Unit.
