Discuss several ways that the magnetic field of a permanent magnet can be destroyed or reversed.
Relevant Questions(a) As you start in the very middle of Fig. 19.3b and move horizontally to the right, what happens to the magnetic field spacing as indicated by the iron filing pat-tern? What does this imply in terms of the magnetic field ...You want to deflect a positively charged particle in an S- shaped path, as shown in Fig. 19.33b, using only magnetic fields. (a) Explain how this could be done by using magnetic fields perpendicular to the plane of the ...A charged particle travels undeflected through per-pendicular electric and magnetic fields whose magnitudes are 3000 N/C and 30mT, respectively. Find the speed of the particle if it is (a) A proton and (b) An alpha ...A 2.0-m length of straight wire carries a current of 20 A in a uniform magnetic field of 50 mT whose direction is at an angle of 37o from the direction of the current. Find the force on the wire. Two bar very narrow magnets are located in the x-y plane. Magnet # 1 lies on the x-axis and its north end is at x = +1.0cm, while its south end is at x = + 5.0cm. Magnet # 2 lies on the y-axis and its north end is at y = + ...
