3. Determine the magnitude and direction of the magnetic field for an electron moving upward through a uniform magnetic field with a speed of 3.5 x 10 m/s. 4K The particle experiences a maximum magnetic force of 7.5 x 10 *N [right]. 1C 4. A 60 cm wire carrying a current of 1.5 A to the left is levitating in a region of the magnetic field. If the mass of the wire is 2 grams, what is the strength and direction 4T of the magnetic field needed to suspend the wire? 1C
