A straight wire carrying a 5.0 A current is in a uniform magnetic field perpendicular to the wire. When
0.10 m of the wire is in the field, the force on the wire is 0.20 N. What is the strength of the magnetic
field?
A wire that is 0.50 m long and carrying a current of 8.0 A is at right angles to a 0.40 T magnetic field.
How strong is the force that acts on the wire?
A wire that is 75 cm long and carrying 6.0 A of current is at right angles to a uniform magnetic field. The
force acting on the wire is 0.60 N. How strong is the magnetic field?
How much current will be required to produce a force of 0.38 N on a 0.15 m wire that is perpendicular to a
uniform magnetic field with a strength of 0.49 T?
What is the force on a 0.25 cm straight wire in a uniform magnetic field of 1.9 T if the current through the
wire is 25 A?
How long is a wire that is at right angles to a 0.15 T magnetic field, if the force acting on the wire is 0.35 N
and the current through it is 5.5 A?
A beam of electrons travels at 2.7 x 106 m/s through a uniform magnetic field of 4 x 10-2 T.
If each electron has a charge of 1.6 x 10-19 C, then what force does each electron experience as it moves
through the field?
A muon travels at 4.21 x 107 m/s through a magnetic field. It experiences a force of 5.0 x 10-12 N. A
muon has the same charge as an electron, 1.6 x 10-19 C. What is the strength of the magnetic field?
How fast does an electron move through a magnetic field with a strength of 0.63 T if it experiences a force
of 4.8 x 10-13 N? (Hint: what is the charge on an electron?)
What is the charge on a particle that moves at 9.0 x 106 m/s at right angles through a uniform magnetic
field with a strength of 4.0 x 10-2 T, if the force acting on it is 8.6 x 10-16 N?
