perpendicular to the magnetic field direction
The polarity of the magnetic field of a wire reverses when you change the direction of the current in the wire.
The conducting wire wrapped around the compass is energized creating a magnetic field that counteracts the effects of the Earth's magnetic field and changes the direction of the compass needle.
TEM TE modes (Transverse Electric) have no electric field in the direction of propagation. * TM modes (Transverse Magnetic) have no magnetic field in the direction of propagation. * TEM modes (Transverse ElectroMagnetic) have no electric nor magnetic field in the direction of propagation. * Hybrid modes are those which have both electric and magnetic field components in the direction of propagation
A magnetic field line shows the direction a compass needle would point
You can reverse the direction of the magnetic field by reversing the direction of the electrical current.
Earth's magnetic field lines up in a direction opposite of the present magnetic Feld
The magnetic field reverses direction.
The magnetic field would reverse.
perpendicular to the magnetic field direction
The magnetic field collapses to zero, then builds up again for the current in the opposite direction.
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.
The direction of magnetic field lines are from north to south
It is a way of representing the magnetic force at a point in the field. The magnitude and direction of the vector represents the strength and the direction of the magnetic force acting on a charged particle in the field.
The direction of a magnetic field is defined by the direction in which a compass needle will point when placed within that field -that is, from north to south.
A magnetic field is neither: it is a vector field with both direction and quantity.
The polarity of the magnetic field of a wire reverses when you change the direction of the current in the wire.
