A circular loop with a diameter of 1 511 cm lies on a horizontal plane as viewed from above. Through it is a 3.3 A of current moving clockwise. What is the magnitude and direction of the magnetic field at the center of the loop? 2. An electron is moving to the x at EDD x 105 mls through a uniform magnetic field of 1.4 x 104 T along the +v. What is the magnitude and direction of the force if the velocity of the electron and the magnetic field are perpendicular to one another? 3. The hot and neutral wires supplying DC power to a light-rail commuter train carry map A and are separated by \"IUD cm. What is the magnitude and direction of the force between 50 m of these wires? 4. A helix of six circular loops of radius ?' cm carries current of 2.5 A. The ow is seen as counter-clockwise when viewed along a line perpendicular to the loops formed. What is the magnitude and direction of magnetic field that this solenoid is creating
