Calculate with what force the magnetic field created by the current acts on the conductor if the magnetic induction

Calculate with what force the magnetic field created by the current acts on the conductor if the magnetic induction of the field is B = 1.5 T, the working length of the conductor is L = 0.4 and a current I = 50A flows through it.

B = 1.5 T.

L = 0.4 m.

I = 50 A.

Fump -?

On a conductor of length L, through which a current flows with a current strength I, in a magnetic field with induction B, the Ampere force Famp acts, the value of which is determined by the formula: Famp = I * B * L * sinα, where ∠α is the angle between the direction of the current in the conductor and vector of magnetic induction B.

We will assume that the conductor is located perpendicular to the lines of magnetic induction, therefore ∠α = 900, sin900 = 1.

The formula for determining the Ampere force Famp will take the form: Famp = I * B * L.

Famp = 50 A * 1.5 T * 0.4 m = 30 N.

Answer: Ampere force Famp = 30 N. acts on a conductor with current, when it is perpendicular to the lines of magnetic induction.
