A teacher used the equipment shown in the image below to demonstrate the motor effect. Increasing the current can increase the force acting on the copper rod. Give the way in which the size of the force acting on the copper rod could be increased. Explain your answer.

From the picture below, 1. Predict which direction of force a positively charged particle will feel at the instant the charged particle enters this magnetic field (which is coming out of the screen) from the left? 2. Predict how is the path the negatively charged particle traces different from the positively charged particle if the charged particle now has a negative charge (make sure the magnetic field is still pointing out of the scrren)

Assessment 1 Directions: Choose the best answer from the choices in the parenthesis. Write your answer on a separate sheet of paper. 1.A generator is a machine which converts Mechanical Energy into (Chemical, Electrical). 2. Generator (uses, produces) electricity, hence, the glowing of the LED lights when rotation takes place. 3. The generator is used to produce an electric current from (rotational, diagonal) motion of the CD with handle. 4. Generator works on (Michael Faraday's, Christian Oersted's) Electromagnetic induction. 5. On a large scale power station like the hydroelectric power plant (San Roque Dam) a (propeller, turbine) is used to provide the rotation.

1Discuss how the alignment of atoms makes a magnet weak or strong. Use the term magnetic domain in your discussion.   2Which of the following are true regarding Earth’s magnetic field? Check all that apply.     the magnetic poles drift about 10-15 km per year   scientists are not really sure why Earth acts like a magnet   the magnetic north pole is actually the south pole of Earth’s “magnet”   the magnetic north pole is stationary 3You heat up a piece of metal and bring it close to a strong magnet. You let the piece of metal cool while in place. What happens?   The induced magnet will stay a magnet after it cools.   Nothing happens in this case, because there was no contact between the metal and strong magnet.   The magnetic ability of the original strong magnet will be reduced by the presence of the non-magnetic material.   After the induced magnet is moved away from the strong magnet, it will return to its non-magnetic form.
