Question 1.
What does a compass needle indicate when placed near a current-carrying wire?
Show hintHide hint
Think about how magnets interact with compass needles.
Question 2.
What rule do we use to find the magnetic field direction around a wire?
Show hintHide hint
Consider how you might hold the wire with your right hand.
3Question 3.
What happens to the magnetic field when the direction of the current is reversed?
- It remains the same
- It reverses
- It disappears
Show hintHide hint
Think about the right-hand thumb rule.
4Question 4.
True or False: The strength of magnetic field decreases with the increase in distance from the conductor.
- True
- False
Show hintHide hint
Remember how we discussed distance affects strength.
Question 5.
If a straight wire carrying a current of 6 A is placed in a magnetic field of uniform strength, how would the angle of the wire with respect to the magnetic field affect the force experienced by the wire?
Show hintHide hint
Think about the right angles maximizing the force.
Question 6.
Design an experiment to compare the strength of the magnetic fields produced by a straight wire and a circular loop. What results would you expect?
Show hintHide hint
Consider how the shape of the conductor influences the magnetic field.
