A washer with inner diameter 5.0 cm is carried in your pocket as you walk directly north according to your magnetic compass. Assume the normal to the washer's plane is exactly horizontal, pointing toward magnetic north. The Earth's magnetic field strength is 0.056 mT. If the magnetic flux through the washer's opening is 36 nTm2, what is the angle below local horizontal that the magnetic field vector points?

A proton travels at a speed 1.1 × 107 m/s perpendicular to a magnetic field. The field provokes the proton to move in a circular path of radius 0.975 m. What is the field strength, in tesla?

The figure below shows two wires carrying currents of I = 4.55 A in opposite directions, separated by a distance d. Assume d = 8.3 cm. (a)Find the magnitude (in µT) and direction of the net magnetic field at a point halfway between the wires. what is the magnitude µTdirection, (b)Find the magnitude (in µT) and direction of the net magnetic field at point P1, 8.3 cm to the right of the wire on the right. magnitude µTdirection, (c)Find the magnitude (in µT) and direction of the net magnetic field at point P2, 2d = 16.6 cm to the left of the wire on the left. magnitude µTdirection, (d) What If? Repeat parts (a) through (c) for the case where both wires carry currents in the same direction, upward in the figure.Find the magnitude (in µT) and direction of the net magnetic field at a point halfway between the wires. magnitude µTdirection, Find the magnitude (in µT) and direction of the net magnetic field at point P1, 8.3 cm to the right of the wire on the right. magnitude µTdirection, Find…

The figure below shows the cross section of a long cylindrical conducting cylinder of radius a = 0.0896 m. The current density in the cross section is given by J = (7.66 × 106 A/m³) r. Where inside the cylinder does the magnetic field have a magnitude of 1.08 × 10-³ T? i m a r
