Lesson 1: Magnetic Fields 1. In the diagram below, a compass is placed under the conductor and the conductor is carrying conventional current from A to B. In which direction will the compass needle point? answer here 2. In the diagram below, a compass is placed over a conductor and the conductor is carrying electrons from B to A. In which direction will the compass needle point O 3. In the diagram below, the compass is pointing toward the right side of the page. In which direction is current flowing in the conductor, A to B or B to A? to CBe-Learn Physics 30 Module 4 Assignment October 2020 4 . In the diagram below, the circle represents the cross-section of a conductor coming out of the page. The direction of the current is represented by the dot in the centre of the conductor. In what direction will a compass needle point if it is placed at point P? P .5. In the diagram, electrons are flowing from A to B. Which end of the solenoid becomes the north pole? A 6. In the diagram, current is flowing from A to B. Which end of the solenoid becomes the south pole? B A 7. In the diagram, the top of the solenoid is the induced north pole. Which way is the current flowing, A to B or B to A? B 8. Draw the magnetic field lines for the following configurations. Indicate whether the objects experience an attractive or repulsive magnetic force. Do the drawings on a separate piece of paper. (Do not cram them onto this page.)

If you fire a positively charged bullet horizontally and watch it recede away from you, what is the direction of the magnetic field that surrounds it? (clockwise or counterclockwise) 10. Is the North Magnetic Pole area on Earth a North Pole or a South Pole? Explain using a diagram of the Earth's magnetic field
