Why Do transverse magnetic mode has no magnetic line is in direction of propagation?
No. It has. Since transverse electric mode has it's wave propagating in the Z direction, and has magnetic field existing in the same direction with NO electric field... Likewise, transverse magnetic mode has it's wave propagating in the Z direction and has electric field existing in the same direction with NO magnetic field.
Could a magnetic field be electrons flowing through power lines?
A magnetic field is caused by flowing currents, but the field lines are not directly related to the flow of electrons or other charged particles. They are simply an abstraction that tells you where the magnetic attraction is strongest, and in what direction it goes.
Why do people use magnetic north?
Because that's the direction a magnetic compass points to.
What is a group of atoms with their magnetic poles pointed the same direction?
A magnet, or a magnetic domain.
What instrument is used for determining direction?
A compass. The North magnetic pole is in the direction of the N on the compass. Therefore, the North magnetic pole is in fact a magnetic field south pole since it *attracts* the north magnetic field pole of the compass magnet.
In north America a manetic compass will point to?
It points in a northerly direction towards the North Magnetic Pole (which is close to, but not the same as the North Pole)
What is the direction of magnetic filed lines?
The direction of magnetic field lines are from north to south
How can you reverse the direction of the magnetic field in a wire produced by an electric current?
You can reverse the direction of the magnetic field by reversing the direction of the electrical current.
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.

The force on an electron moving in a magnetic field will be the largest when its direction is?
perpendicular to the magnetic field direction

A magnetic compass indicates direction because?
Earth has magnetic properties
What is magnetic bearing?
It is a bearing (a direction) based on a magnetic compass reading.
What happens to magnetic field of a wire when you change the direction of the current in the wire?
Direction of the magnetic lines too would get changed
What happen to the magnetic field of a wire when change the direction of the current in the wire?
Direction of the magnetic lines too would get changed
Why electromagnets work?
When you wrap the wire around the nail, make certain that you wrap the wire all in one direction. You need to do this because the direction of a magnet field depends on the direction of the electric current creating it. The movement of electric charges creates a magnetic field. If you could see the magnetic field around a wire that has electricity flowing through it, it would look like a series of circles around the wire. If an electric current is flowing directly towards you, the magnetic field created by it circles around the wire in a counter-clockwise direction. If the direction of the electric current is reversed, the magnetic field reverses also and circles the wire in a clockwise direction. If you wrap some of the wire around the nail in one direction and some of the wire in the other direction, the magnetic fields from the different sections fight each other and cancel out, reducing the strength of your magnet.How_does_a_electromagnet_work
