Answer:
The angle wires have to be placed to experience full force is such that the angle between the direction of current flow and the direction of the magnetic field is 90°
Explanation:
The direction of the force acting on a conductor through which a charge flows is given by Flemings Left Hand Rule which states that the direction of the force acting on a conductor carrying a current of charge is perpendicular to both the direction in which the current is flowing and the direction of the magnetic field
Therefore, wires carrying flowing charges has to be placed such that the direction of charge (current) flow is perpendicular (at 90°) to an existing magnetic field to experience (maximum) full force
Explanation:
Given that,
Induced emf
Rate of current = 0.250 A/s
Number of turns =30
(a). We need to calculate the mutual inductance of the pair of coils
Using formula of the mutual inductance
The mutual inductance of the pair of coils is 6.6 mHz.
(b). We need to calculate the flux through each turn
Using formula of flux
Put the value into the formula
The flux through each turn is
(c). We need to calculate the magnitude of the induced emf in the first coil
Using formula of induced emf
The magnitude of the induced emf in the first coil is
Hence, This is the required solution.
Answer:
force on electron will be equal to
Explanation:
We have given magnitude of electric field E = 600 N/C
Charge on electron
We have to find the electric force on the electron
Force in electric field is equal to , here q is charge and E is electric field
So force will be equal to
So force on electron will be equal to
Answer:
true
Explanation:
Yes, it is true.
As the wattage is more than the prescribed wattage, it becomes overheated.
