Question

Determine which of the following statements are correct or incorrect. If a statement is incorrect, explain how you could change it slightly to fix it. "Those strong neodymium magnets from lab pull on the weak bar magnets with a lot more force than the weak magnets pull on the strong magnets." "It's impossible to use Ampere's Law inside a wire because there's no way to get an Amperian loop through the solid metal." "That 2 meter long wire has an enormous voltage - the entire wire is at a constant 10,000V. There must be a huge electric field inside!"

Explanation / Answer

1) False

This can be changed to " My cell is charged up with 5 C of charge".

2) False

Both magnets pull each other with same force.The force is same on each other.

3) False

Because ampere's law states that Magnetic field around a wire is proportional to the current in the wire. So " It's possible to use Ampere's law inside a wire but the current is the one enclosed in the loop we consider".

4) False

"If the wire is at high Voltage then there must be a huge current flow inside"
