-Explain, using the domain theory, why a needle is magnetized when it is rubbed in one direction with a strong magnet.
-An electron accelerates from rest through an electric field and into a magnetic field as shown in the diagram below. The plates have a potential difference of 25 V, and the magnetic field has a magnitude of 0.50 T. (Remember: me = 9.1 × 10-31 kg and e = 1.6 × 10-19 C.)
(a) Calculate the initial speed of the electron upon entering the magnetic field.
(b) Calculate the magnitude and direction of the magnetic force on the electron.
(c) Calculate the radius of the electron's circular path.
-Draw a straight current-carrying conductor showing its magnetic field and the direction of current flow.
