Homework Answers
Answer:
The direction of an electric current is by convention the direction in which positive charge would move. Hence electric current in the electrical circuit is directed away from the positive terminal and towards negative terminal of the battery. In this case the positive ions are moving to the left so the correct option is - to the left.

Objective: To perform some calculations involving magnetic forces on charged particles, and involving magnetic flux created by a magnetic field. 1. An electron is moving in the +x direction at a constant speed in a region of space. a. If there is no external magnetic field (that is, no magnetic field beyond that created by the electron), what is the strength of the external electric field in this region of space? Justify your answer in terms of forces. b. If...

Which property is observed when a beam of charged particles is fired into a magnetic field?...
Which property is observed when a beam of charged particles is fired into a magnetic field? If the beam of charged particles is parallel to the magnetic field, no deflection will occur. The maximum deflection happens when the beam is perpendicular to the magnetic field. The magnitude of the magnetic deflecting force is directly proportional to the magnitude of the charge on each particle. The magnetic deflecting force is always perpendicular to the direction of travel of the charge and...

Part A In a region of space, a magnetic field points in the +x-direction (toward the right). Its magnitude varies with position according to the formula B = Bo + bx, where Bo and b are positive constants, for 3 > 0. A flat coil of area A moves with uniform speed v from right to left with the plane of its area always perpendicular to this field. What is the emf induced in this coil while it is to...
