How do you calculate the size of a magnetic field?

Example

1. 5.0 cm = 5 ÷ 100 = 0.050 m.
2. force on a conductor carrying a current = magnetic flux density × current × length.
3. force = 0.60 × 0.75 × 0.050.
4. force = 0.0225 N.

How do you determine the shape of the current magnetic field?

Coil the fingers of the right hand as if holding the handlebars of a bicycle, with the thumb pointing away from the hand. The thumb indicates the direction of the current, and the fingers then indicate the direction of the magnetic field.

How do you calculate the electric field of a magnetic field?

F = q (E + v × B). The electric displacement D and magnetic intensity H are related to the electric field and magnetic flux density by the constitutive relations: D = ε E, B = µ H.

What is the shape of the magnetic field lines around wire?

What is the shape of the magnetic field lines around a current carrying straight wire? They are concentric circles.

What is the general direction and shape of magnetic field?

Magnetic field lines are continuous, forming closed loops without beginning or end. They go from the north pole to the south pole.

What is the shape of a magnetic field?

Magnetic field lines form in concentric circles around a cylindrical current-carrying conductor, such as a length of wire. The direction of such a magnetic field can be determined by using the “right-hand grip rule” (see figure at right).

How can you find the direction of magnetic field from a magnetic field lines?

The direction of a magnetic field at a point is determined by placing a small compass needle. The N – pole of compass indicates the direction of magnetic field at that point.

How do you find the electric field size?

the magnitude of the electric field (E) produced by a point charge with a charge of magnitude Q, at a point a distance r away from the point charge, is given by the equation E = kQ/r2, where k is a constant with a value of 8.99 x 109 N m2/C2.

How many shapes does a magnet have?

They can be made into a bar, rectangle, block, horseshoes, round, rings, donuts, disc, segment, bread, multi-fingered rings, or other custom shapes. Every shape of magnets is customized based on their application.

Why are magnets in different shapes and sizes?

Magnets come in many different shapes and sizes. These shapes reflect the individual strength of each magnet. The strength determines function.
