Answer:
y(n) = 0.99 y(n-1) + x(n)
Answer:
I = 4.642 Ampere.
x = 2.145 cm
Explanation:
a) As we know, the magnetic field on the axis of the loop is given as
where a = radius of loop
x = point on the axis of loop
N = No of turns of coil
Current in the loop for which the magnetic field at the center is 0.0750 Tesla is given as x = 0
Therefore, the above equation can be rewritten as
I =
by putting values
I =
Current in the loop for which the magnetic field at the center is 0.0750 Tesla = I = 4.642 Ampere
b)
Now for part b the magnetic field at a distance x from the center is given as
multiply and divide by a on both sides we get
As we know, according to Biot sivorts law,the Magnetic Field at the Center of a circular loop is given as
( Magnetic field at center) =
So we got magnetic field at any point x as
= X
For magnetic field at x is half of the B at center
=
from the above two equations
=
Putting a = 2.80 cm
We have x = 2.145 cm Ans

Explanation:
J is between H and K. If HJ=6x-5, JK=4x-6 and KH= 129, find the value of HJ
Answer:
The motor works based on the principle of electro magnetic induction
Explanation:
According to the principle of electro magnetic induction, when a wound coil is made to rotate around a magnetic field an emf is induced in the coil which is equal to the strength of the magnetic field.
A motor is an electrical machine which converts electrical energy into mechanical energy.
The motor consists of a rotor, a coil wound around a shaft and a magnetic field
