What is the length of the conductor, if in a magnetic field with an induction of 0.25 T, a magnetic force of 2H acts on it and the current in the conductor is 5A.
B = 0.25 T.
Fa = 2 N.
I = 5 A.
∠α = 90 °.
L -?
A conductor with a current in a magnetic field is acted upon by the Ampere force Fа, the value of which is determined by the formula: Fа = I * B * L * sinα, where I is the current in the conductor, B is the magnetic induction of the magnetic field, L is the length of the conductor, ∠α – the angle between the direction of the current and the magnetic induction B.
L = Fa / I * B * sinα.
L = 2 N / 5 A * 0.25 A * sin90 ° = 1.6 m.
Answer: the length of the conductor is L = 1.6 m.
