A conductor with an electric current in a magnetic field is acted upon by the Ampere force Famp, which is determined by the formula: Famp = I * L * B * sinα. Where I is the current in the conductor, is the length of the conductor, B is the modulus of the magnetic induction vector, α is the angle between the magnetic induction vector B and the direction of the current in the conductor I.
Ampere force Famp = 0 when sinα = 0. α = 0.180.
Answer: Ampere’s electromagnetic force is 0 when the conductor with current is located along the lines of magnetic induction.
