Answer:
The magnitude of the magnetic field inside the solenoid is 1.5 × 10⁻²T
Explanation:
Given that,
Length = 40 cm
Radius = 0.040 cm
Number of turns = 400
Current = 12 A
We need to calculate the magnetic field
Using formula of magnetic field inside the solenoid
Where,
=Number of turns per unit length
I = current
B = magnetic field
Put the value into the formula
Hence, The magnitude of the magnetic field inside the solenoid is 1.5 × 10⁻²T

Answer:
Sometimes
Explanation:
Sometimes meaning in occasions. If it is a "vampire star" not likely because they also cause they also make novas happen by sucking the gas from another star.
