Current from magnetic force
A wire in a school transformer demonstration experiences force \(0.18\,\text{N}\) in a \(0.55\,\text{T}\) magnetic field. Active length is \(0.65\,\text{m}\). Calculate current. Use the diagram labels before calculating the requested value. Enter the numerical result and choose the interpretation that matches the field physics.
