If the magnitude of the magnetic field is B what must the magnitude of this field be to cancel out the gravitational force on the wire?

Expert Solution

Answer

Let 'm ' be the mass , L the length and I the current, then at equilibrium condition

Force dut the field = Force due to gravitation

ie BIL = mg

Therefore B = (mg) / ( IL)

Magnitude and direction of the magnetic field

A proton moves perpendicular to a uniform magnetic field B at a speed of 1.30 x 10^7 m/s and experiences an acceleration of 2.40 x 10^13 m/s^2 in the positive x direction when its velocity is in the positive z direction. Determine the magnitude and direction of the field?

A magnetic field has a magnitude of 1.2e-3 T, and an electric field has a magnitude of 5.1e3 N/C. Both fields point in the same direction. A positive -1.8 microC moves at a speed of 3.5e6 m/s in a direction that is perpendicular to both fields. Determine the magnitude of the net force that acts on the charge.

3. A uniform magnetic field of magnitude B = 0.400 T is directed along the positive x axis (see figure). A positron (anti–electron) moving at a speed of v = 3.00 × 103 m·s-1 enters the magnetic field along a direction that makes an angle of 37.0o with the x axis. The mass of the charge is m = 9.1×10-31 kg. a) Write the Lorentz force (in vector form) for the general case and the actual case shown in the...
