4. Given a current of 1.2 A; a coil radius of 0.17 m; and N=130, then what is the strength of the magnetic field in milliTeslas?
(Use three sig figs. or write N/A if there is not enough information.)

5. Let's say that you are given a magnetic field
B = 0.0026 Teslas.

You also have an average V / d 2 = 28,255 V/m 2;
what is the value for e / m ?
units are suppressed
(Report your answer with three sig. figs. and use scientific notation "E". ie. 1.98E11)

    3. A coil consists of 130 circular loops of wire of radius 4.4 cm. A current of 0.46 A runs through the coil, which is oriented vertically and is free to rotate about a vertical axis (parallel to the z-axis). It experiences a uniform horizontal magnetic field in the positive x-direction. When the coil is oriented parallel to the x-axis, a force of 1.2 N applied to the edge of the coil in the positive y-direction can keep it from...
