Question

A permanent magnet has magnetic field lines as shown below. A wire oriented perpendicular to the screen carries a current toward you at point A. The direction of the magnetic force on the wire is best represented by 1. 2. 3. 4. 5. 6. A negatively charged particle is moving upward and to the right in a uniform magnetic field that points in the horizontal direction. What is the direction of the magnetic force on the charge? left right up down into the screen out of the screen no force at all A negative charge is placed at rest in a magnetic field as shown below. What is the direction of the magnetic force on the charge? left right up down into the page out of the page no force at all A permanent magnet has magnetic field lines as shown below. A wire oriented perpendicular to the screen carries a current toward you at point A. The direction of the magnetic force on the wire is best represented by 1. 2. 3. 4. 5. 6.
