A horizontal rectangular surface has dimensions 2.80 cm by 3.20 cm and is in a uniform magnetic field that is directed at an angle of 30.0° above the horizontal. What must the magnitude of the magnetic field be to produce a flux of 3.10x10^-4 Wb through the surface?

A circular area with a radius of 6.50 cm lies in the xy-plane. What is the magnitude of the magnetic flux through this circle due to a uniform magnetic field B = 0.230 T (b) at an angle of 53.1° from the +z-direction?

A flat, square surface with side length 3.40 cm is in the xy-plane at z = 0. Calculate the magnitude of the flux through this surface produced by a magnetic field B=(0.200 T)i+(0.300 T)j-(0.500 T)k .

An electron experiences a magnetic force of magnitude 4.60x10^-15 N when moving at an angle of 60.0° with respect to a magnetic field of magnitude 3.50x10^-3 T. Find the speed of the electron.

Which option best completes the following sentence? If a magnet is carefully balanced, as in a compass, the north end of the magnet points roughly toward…

A wire carries a positive current to the left in the plane of this screen. What is the direction of the magnetic field at a point near the top of the screen, still in the plane of the screen?

At what distance from a wire carrying a 10 Acurrent is the magnetic field strength equal to $50\mu \mathrm{T}$? This is the approximate value of the earth's magnetic field.

Two long parallel wires lie in the $xy$-plane, each carrying a $5.0$ A current in opposite directions. Wire 1 lies along the$y=3.0\mathrm{ cm}$ line and carries a current in the positive $x$-direction; wire 2 lies along the $y=0$ line and carries a current in the negative $x$-direction. What is the magnitude of the magnetic field at the point $\left(0\text{cm,}1\text{.5}\text{cm,}0\mathrm{ cm}\right)$?
