Within a uniform magnetic field B, a straight wire is carrying current in the direction shown in this figure. The direction of this uniform magnetic field is denoted by the blue dots. (Think about what these dots means. This was taught in my lectures.) B. What is the direction of the magnetic force acting on this current-carrying wire? The magnetic force points: A to the right: B. out of the page; C. Into the page: D. to the left; O...
4.A long, straight wire carrying a current moving upward is placed in a magnetic field produced by magnets, what is the direction of the magnetic force acting on the wire? 2 % (A) right, (B) left, (C) upward, (D) downward, (E) into the page, (F) out of the page, (G) Clockwise (H) Counter-clockwise.
3. Explain how the right hand rule will predict the direction of the magnetic field for an electric current running through a coil of wire: 4. Explain how the right hand rule works for an external magnetic field that is changing inside a coil of wire: 5. In the situation below, the bar magnet is moving to the right. What will be the direction of the induced current in the solenoid? (Either draw arrows, or describe like up in front, down in...
