Resistance is where you try to stop something from happening or trying to stop something in general

Answer:

Resistance is a resistive force that goes against a force. Other names for it are : Friction or Drag.

Explanation: Say you're pushing a Box towards the right, you're applying force pushing it in that direction. Now, there's going to be a resistive force pushing on the box as well, moving left. But If you're talking about Electricity, that's another story, Pretty similar tho.

A certain superconducting magnet in the form of a solenoid of length 0.56 m can generate a magnetic field of 6.5 T in its core w

Gnom [1K]

Answer:

The value is $N =36203 \ turns$

Explanation:

From the question we are told that

The length of the solenoid is $l = 0.56 \ m$

The magnetic field is $B = 6.5 \ T$

The current is $I = 80 \ A$

The desired temperature is $T = 4.2 \ K$

Generally the magnetic field is mathematically represented as

$B = \frac{\mu_o * N * I }{L }$

=> $N = \frac{B * L }{\mu_o * I }$

Here $\mu_o$ is the permeability of free space with value

$\mu_o = 4\pi * 10^{-7} N/A^2$

So

$N = \frac{6.5 * 0.56 }{ 4\pi * 10^{-7} * 80 }$

=> $N =36203 \ turns$
