Question

A segment of length L of conductor b, carrying current Ib, is placed in the magnetic field Ba produced by conductor a. The force experienced by this segment is known as the:

विकल्प

• Lorentz force, given by \[F_{ba} = I_b L B_a\]

• Gravitational force, given by \[F_{ba} = I_b L B_a\]

• Lorentz force, given by \[F_{ba} = \frac{I_b L}{B_a}\]

• Electrostatic force, given by \[F_{ba} = \frac{I_b B_a}{L}\]

Answer 1

A segment of length L of conductor b carrying current Ib in the field Ba experiences a Lorentz force Fba = Ib L Ba. Substituting Ba = μ₀Ia/(2πd) gives Fba = (μ₀IaIb/2πd) · L.
