For a straight wire, induced current depends upon?
ایک سیدھی تار کے لیے، حوصلہ افزائی کرنٹ پر منحصر ہے؟
- The speed of movement of wire
- The length of wire
- The magnitude of magnetic flux density
- All of the above
Explanation
For a straight wire, the induced current (I) depends on:
- The speed of movement of the wire (v): The faster the wire moves, the greater the induced current.
- The length of the wire (L): The longer the wire, the greater the induced current.
- The magnitude of the magnetic flux density (B): The stronger the magnetic field, the greater the induced current.
The induced current is given by Faraday's law of induction: I = -BLv
Where:
- I is the induced current
- B is the magnetic flux density
- L is the length of the wire
- v is the speed of movement of the wire
