A long copper wire carries a 6.0-A current in a uniform magnetic field that is applied perpendicular to the 3.0-m segment of the wire, the magnetic force on the segment is 0.36 N. (a) What is the magnitude of the magnetic field? (b) If the segment of wire has a mass of 0.050 kg, and is kept in the same magnetic field as part (a). What minimum current in the wire is needed in order for the magnetic force to cancel the weight of the rod? HTML Editor Keyboard Shortcuts 12pt Paragraph
Homework Answers
Answer #1
As magnetic field is
perpendicular to length of wire, force will be ILB .using this
magnetic field is calculated.
Magnetic field comes out to be 0.02T
b)Magentic force balances weight of rod,using this current can be calculated.
