          A straight, stiff, horizontal wire of length 25 cm and
mass 80 g is connected to a source of emf by light,
flexible leads. A magnetic field of 1.33 T is horizontal and
perpendicular to the wire. Find the current necessary to float the
wire, that is, find the current for which the magnetic force
balances the weight of the wire.

Step 1

First, we need to find the weight of the wire. Weight is given by the formula: Weight = mass × gravity where mass = 80 g = 0.08 kg (converting grams to kilograms) and gravity = 9.81 m/s². Weight = 0.08 kg × 9.81 m/s² = 0.7848 N Show more…
