A point P is halfway between two current-carrying wires separated by 0.10 m. The left wire carries 25 A out of the page while the right wire carries 15 A into the page. W the magnitude of the magnetic field at point P (in tesla)? Give your answer as only the numerical value in the Sl units specified. e is interpreted as x10^ for use with large or small values; 1.01e2 is interpreted as 1.01 x 102.

A proton, that is accelerated from rest through a potential of 60 kV enters the velocity filter, consisting of a parallel-plate capacitor and a magnetic field, shown below. What is the proton's speed? Take т, — 1.67 х 10 27 kg and e - 1.6 x 10 19 с. B The speed, v - Units Select an answer The E-field between the plates is 1.3 x 106 N/C. What B-field is required so that the protons are not deflected? The magnetic field, B = Units Select an answer

A small cart (which you may treat as a point charge) carrying a charge of 3.000 C moves along a straight track at a constant speed of 12.000 m/s. What is the magnitude of the magnetic field at a point beside the track that is 13.000 cm away from the track and 24.000 cm farther down the track than the charged cart? μΤ

6. A wire with length L carries a constant current of I in the +y direction. See figure. It is in a region of space where the magnetic field is given by: B=-B, y (4) L positive constant. If the magnitude of the magnetic force on the wire is F, find Bo. The knowns are F, I and L. Start with dF = Idl x B I i, where Bo is a thickness = dy I L
