i did it and got it right guys i hope it helps a lot
Answer:
Below
Explanation:
● What makes conductors special is that they have some free electrons that can move.
● An insulator has no free electrons wich explains why current isn't transmitted through it.
Answer:
Interchanging the poles of the magnet
Reversing the direction of the applied current
Explanation:
- The working of the electric motor is associated with Fleming's left-hand rule.
- It states that if a current-carrying conductor is placed inside a magnetic field, it experiences a force in the direction perpendicular to the direction of the electric current and magnetic field.
- These three physical quantities are placed in a mutually perpendicular direction.
- So, in order to reverse the direction of force, you have to either change the direction of the current or magnetic field.
There is no diagram below so I can't answer the question
Answer:
metre per seconds
Explanation:
because velocity = distance ÷ time
