Which scenario best illustrates the concept of a 'charged object' as described?
Which scenario best illustrates the concept of a 'charged object' as described?
- A balloon that sticks to a wall after being rubbed against hair. (correct)
- A neutral metal sphere resting on an insulated surface.
- A compass needle pointing towards the Earth's magnetic north.
- A wire through which electrons flow at a steady rate, maintaining electrical equilibrium.
A wire carries a constant electrical current. How does this current primarily relate to magnetic fields?
A wire carries a constant electrical current. How does this current primarily relate to magnetic fields?
- The current produces a magnetic field around the wire. (correct)
- The current will be diminished due to the creation of a magnetic field along the wire.
- The current insulates the wire from being affected by other external magnetic fields.
- The current prevents the formation of a magnetic field outside the wire.
Two charged particles, one positive and one negative, are placed near each other. Which statement accurately describes the interaction between them?
Two charged particles, one positive and one negative, are placed near each other. Which statement accurately describes the interaction between them?
- There will be no interaction between them as the charges cancel out.
- They will initially attract, but then repel once they reach a certain proximity.
- They will attract each other because opposite charges create an attractive force. (correct)
- They will repel each other due to their opposite charges.
A student observes that two magnets repel each other. Which of the following explanations is most likely to describe this observation?
