The magnetic field strength is 17 Weber.
<h3>How can we find the value of magnetic field?</h3>We know, The magnetic field equation is given by:
Where, we know,
=
= It is the magnetic constant or the permeability of free space.
n = The turn density which is equivalent to number of turns per unit length = 3300 turns per meter = 3300
I= the amount of current applied to it = 4. 1 kA = 4 × A.
We have to find the magnetic field strength = B
Substituting the known values into the equation gives the strength of the magnetic field, which is:
[We know,
]
So, from the above calculation we can see that, The magnetic field strength is 17 Weber.

Answer:
F = 3.84*10^-34N ^j
Explanation:
In order to calculate the magnetic force on the electron you use the following formula:
(1)
q: charge of the electron = -1.6*10^-19C
B: magnitude of the magnetic field = 0.80T
v: speed of the charge = 3.0*10^5 m/s
The direction of the motion of the electron is in the +i^ direction (+x direction). The magnetic field is in the +^k direction (+z direction).
The cross product between these unit vectors, by taking into account the minus sign of the charge, is given by:
-^i X ^k = ^j
The magnetic force is in the ^j direction (+y direction).
The magnitude of the magnetic force is:
The magnetic force on the electron has a magnitude of 3.84*10^-34N in the +y direction
