Question

2. Based on the direction of current flow and direction of magnetic field, which direction will the loop of wire within the magnetic field turn? Explain your reasoning 3. A simple circuit is set up. 1. Explain how and why an ammeter and a voltmeter is placed into the circuit to perform measurements based upon the internal design of each. 4. A set of batteries are put into a circuit. 1. Explain if how it is possible for the terminal voltage to be less than, equal to, and or greater than the emf of the batteries. b. Discuss how the batteries can be arranged to reduce internal resistance, and the affect this would have on the terminal voltage 5. What is the direction of the magnetic force on a positive charge and a negative charge that moves as shown in each case shown? Be clear for each. OOOO OOOO oooo 6. State/diagram the direction of the magnetic field for the following solenoids. Be clear for cach. 7. What are the signs of the charges for each of the particles a, b, and e? Explain your reasoning

please answer questions 2,4,6

Answer 1

ONE QUESTION AT A TIME, PLEASE

2)

use right-hand rule,

the force on the lower side is to the left and force on the upper side is to the right, so the rotation will be clockwise as seen from the side as shown

4)

(a) the emf of the battery is always greater than the terminal voltage because when connected to a circuit, the voltage reduces because of the internal resistance of the voltage source.

(b) The batteries can be arranged in parallel to decrease overall internal resistance.

6)

Just use right-hand rule, the current leaves the positive terminal.
