The diagram below shows three equally spaced wires that are perpendicular to the page. The currents are all equal, two being out of the page and one being into the page. Rank the wires according to the magnitudes of the magnetic 1 2 3 forces on them, from least to greatest. Use only numbers 1 - 3 and the signs "<" and "=" in your answer.

The velocity vector represents the motion of a (+) charge. The direction of the magnetic force is which of the following? Up, Down, Left, Right, Into the page, Out of the page or No Force? (X)

The accompanying figure shows a long, straight wire carrying a current of 10 A. What is the magnetic force on an electron at the instant it is 20 cm from the wire, traveling parallel to the wire with a speed of 2.0×105m/s?2.0×105m/s? Describe qualitatively the subsequent motion of the electron.

A long straight wire carries a 1.5 A current. An electron moves parallel to the wire at speed 3.1 x 104 m/s. The distance between the electron and the wire is 8 cm. Calculate the magnitude of the magnetic force on the electron.(Give your answer in newtons but don't include the units.)

Two long parallel wires carry currents of 2.15 A and 7.55 A. The magnitude of the force per unit length acting on each wire is 6.21 x 10-5 N/m. Find the separation distance d of the wires expressed in millimeters. d = mm

A 14.29m wire carries a current of 76.32mA perpendicular to a uniform magnetic field of magnitude 2.99T. What is the magnitude of the force the wire experiences due to the presence of the magnetic field? Note: It is understood that the unit of your answer is in Newtons, however do not explicitly include units in your answer. Enter only a number. If you do enter a unit, your answer will be counted wrong.

The magnetic field of the Earth is similar in shape to that of a bar magnet, as shown in the figure. If a proton from space enters the Earth's magnetic field to the left of the Earth, with a velocity of 8x107 m/s directed into the page, and the Earth has a magnetic field strength of 1x10-5 T at this location; a) What is the magnitude of the force acting on the proton? b) What is the direction of the force acting on the proton? c) What is the radius of the resulting circular trajectory that the proton will follow?

A long straight wire carries a 1.5 A current. An electron moves parallel to the wire at speed 1.3 x 104 m/s. The distance between the electron and the wire is 7 cm. Calculate the magnitude of the magnetic force on the electron.(Give your answer in newtons. Don't round your answer.)

Two long parallel wires carry currents of 3.39 A and 4.13 A. The magnitude of the force per unit length acting on each wire is 5.33 x 10-5 N/m. Find the separation distance d of the wires expressed in millimeters. d = mm
