A ball rolling down a hill feels a gravitation force. A positive charge rolling down an electric potential feels this kind of force?
What is electric?
A battery moves current through a wire. Moving charges set up a magnetic field. If you run this process in reverse, the following one of these is created.
What is an EMF?
This does NOT move freely on an insulator.
What is charge?
The unit that describes an energy per unit charge.
What is volt?
A positive charge sits at the origin. This is how you would describe the electric potential close to the origin relative to out at infinity.
What is large?
Work Done is the product of force times distance. In a uniform electric field, the work done on a charged particle, qtest, is this.
What is qtestE*deltax?
changing B field strength, B field direction, area of a loop and orientation of a loop can all cause a change in this.
What is a change in magnetic flux?
A Magnetic Field is set up by charge moving with this.
What is constant velocity?
A bar magnet is completely interchangeable with one of these, which does its best to align with an external magnetic field.
What is magnetic moment?
A positive charge is released from rest in an Electric Field that points upwards. The charge will move like this.
What is upwards?
A 10 nC charge at the origin interacts with a 1 nC charge at x = 10 cm and y = 0 cm. The force that the 1nC charge feels due to the 10nC charge is this amount relative to the force the 10 nC charge feels due to the 1 nC charge.
What is the same?
A long straight wire carries current to the right. The Bfield above the wire points in this direction, while the Bfield below the wire points in this direction.
What is out of and into the page?
Charge moving on a wire under the influence of a battery.
What is current?
If you put both of your index fingers on an electric fence, you will essential create a closed one of these that passes this through your body.
WHat is closed loop and current?
I drop a positive charge in an electric field that points downward. The work done on the positive charge is described as this.
What is positive?
Just as the electric field tells us how the source charges would exert a force on any test charge q, the electric potential tells us how the source charges would provide any test charge with this.
What is energy?
a positive charge moves to the right in a uniform magnetic field. The B field points out of the page. The charge hence feels a force in this direction.
What is downward?
The induced B field points in the direction opposite of this.
What is the direction of the change in the magnetic flux?
A stationary charge in space sets up one of these.
What is an electric field?
A positive charge is repelled from a positive charge. A positive charge is attracted to a negative charge. A positive charge all on its own, in empty space, with nothing around, still has this.
What is an Electric Field?
B fields exert forces on wires. B fields exert this on loops of wires.
What is a torque?
An equipotential surface can also be described by this?
What is contour plot?
The outer surface of a neutral conductor with a hole in it has a charge of +q. This is what you can expect to find inside the hole.
What is a + q charge?
A charge moving with a constant velocity sets up one of these.
What is a magnetic field?
