How is Magnetic flux in a rectangular loop directly related to Magnetic force?
Magnetic flux through a loop is just a measurement of the strength of the magnetic field passing through the loop, and since magnetic field strength is directly related to magnetic force, magnetic force is directly related to the magnetic flux passing through the loop.
Why do wires turn hot in a circut?
The current passing through them - since all wires have resistance.
Why does the light bulb not work when the filament is broken?
A light bulb works by passing an electric current through the filament, which is usually made from a high resistance substance such as tungsten. When the current flows through, the filament glows which produces the light. When it burns out, no electricity passes and no glowing occurs. Source: i just know
How can you use a solenoid to make a temporal magnet?
Passing it through a coil that has a DC current through it. The DC current creates a field which allows the realignment of electrons in the solenoid, allowing it to have temporary magnetic properties. Passing an AC current through the coil would demagnetize the solenoid.
Does coil of wire with current passing through it magnetise a piece of iron?
yes it does the current flows in a wire it creates a magnetic field around the wire.

What will happen if the reading of ammeter a2 after passing through 30 ohm resistance if reading of a1 is 3A after passing through 20 ohm resistance if both are parallel to each other?
5 A
Does salt water passing through a magnet create electricity?
no salt is non magnetic
Passing an electric current through a certain substance produces oxygen and sulfur This substance cannot be a?
Element.
What is the cause of resistance and how the resistance and how the resistance of a wire can be determined?
Electrical resistance can be determined by the equation that defines resistance - Ohm's Law. Just divide the voltage across a resistor, by the current passing through it.
When there is no current passing through a conductor you say magnetic field is zero but in a conductor charges are in motion then why is there no magnetic field?
When there is no current passing through a conductor, charges are stilll in motion, but they are disorganized and not flowing. The magnetic fields by all of those random movements cancel each other out. That is why there is no magnetic field in a conductor with no current, even though there is movement in the charges.
When does an electromagnet produce a magnetic field?
A magnetic field is generated whenever a current is passing through a wire.
Air passing through the texture of a ball?
What is resistance? We're not playing Jeopardy here, people!

For separation of copper and iron what you can use?
you can use magnetic separation by passing a magnet through the copper and iron
Are lines on a chart passing through all places on earth having the same value of magnetic force?
No.
How electron beams fucossed?
Passing through (or along) strong magnetic fields. Eg. in an electron microscope.
