- Semiconductor<br/>with a current is placed in a magnetic field perpendicular to the<br/>current and it induced electric field in the direction. This<br/>phenomenon is known as the ______ .
- What creates a magnetic field? More than one answer may be correct. A: a<br/>stationary object with electric charge B: a stationary conductor carrying electric current C: a<br/>difference in electric potential D: a<br/>charged capacitor disconnected from a battery and at rest
- On the ideal conductor surface, the relationship between the electric field lines and the conductor surface is A: the electric field lines is always pertendicular to the conductor surface. B: the electric field lines is always parallel to the conductor surface. C: there is no electri field lines exsited. D: unable to determine the relationship.
- The<br/>magnetic field lines are used to visually describe the distribution<br/>of the magnetic field around the magnet. For the following<br/>statement,( <br/>) is wrong. A: Each<br/>magnetic field line is a closed loop curve B: No<br/>two magnetic field lines can cross each other C: The<br/>length of the magnetic field line reflects the strength of the<br/>magnetic field D: The<br/>tangential direction of any point on any of the magnetic lines is the<br/>direction of the magnetic field at that point
