Magnetic Force: what is Magnetic Force - Education and Transformation

THE magnetic force it can be attractive or repulsive and appears in electrically charged bodies that are in motion relative to an external magnetic field.

For this force to be measured in Newtons (N), the modulus of the net charge (q) of the body, the excess or lack of charge, must be given in Coulombs. The particle velocity (v) with respect to the magnetic field must be in m/s.

The angle formed between the velocity (v) and the magnetic field (B) in Tesla (T), must be given in degrees (º). These three quantities are always perpendicular.

If the angle formed between the velocity vector (v) and the magnetic field vector (B) is equal to 0º. If they are parallel to each other, there will be no magnetic force arising.

The greatest intensity of magnetic force appears when the angle between v and B is 90°. For this angle, sin (0) has its maximum value, being 1.

Magnetic force on straight conductors

If a straight wire is being traversed by an electric current in a region where there is an external magnetic field, it will suffer the action of magnetic force.

B = value of magnetic field strength in Tesla (T)

i = value of electric current in Amperes (A)

L = wire length in meters (m)

Here the angle is formed between the magnetic field and the length of the wire and therefore must be straight. If it were the other way around, it would be necessary to calculate the magnetic force on each piece of wire that presents a different angle.

1. THE magnetic force it is always perpendicular, 90 degrees, to the velocity of the charged particle and the magnetic field at the same time.
2. As this force makes an angle of 90º with the particle's velocity, this velocity does not change, only its direction and direction are changed, the strengthmagnetic does not perform work.
3. If the angle between the velocity and the magnetic field is 0º, there won't be magnetic force.
