A wire 0.80m long carrying a current of 3.2A is perpendicular to a 0.15T magnetic field (B field). What

is the force on the wire? (Use F=BIL to solve!)

Input answer with 3 decimal places (for example: 555) and do NOT include the units!

E

1.344 N

Explanation:

The expression for the for on a wire carrying current in a magnetic field is given as,

F = BILsinФ Equation 1

Where F = Force on the wire, B = magnetic field, I = current, L = Length of the wire, Ф = angle between the conductor and the magnetic field.

Given: B = 0.15 T, I = 3.2 A, L = 0.8 m, Ф = 90° (perpendicular)

Substitute into equation 1

F = 0.15(3.2)(0.8)(sin90°)

F = 1.344 N

Hence the Force on the wire = 1.344 N

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19
