Answer:
It's a strength or force
Explanation:
the quantity of motion of a moving body, measured as a product of its mass and velocity
When a current is established in a closed conducting loop , we use ammeter. Due to this resultant potential developed detected by voltmeter.
- When current flows through loop , it gets conducted.
- Due to this Electric field is generated . This happens due to induced magnetic field.
- The free electrons were at rest until current is there , still ammeter detects some deflection.
- This deflection is due to zero current.
- Due to magnetic field , current in coil changes.
- Mathematically,
- The presence of conducting loop is not necessary for having electric field.
i=0.63 io
