The force on an electron moving in a magnetic field will be the largest when its direction is?
perpendicular to the magnetic field direction
Why and when does a current carrying conductor kept in a magnetic field experiences a force list factor on which the direction of this force depend State the rule which may be used to determine the di?
Current carrying conductor will have magnetic lines around it. So when it is kept perpendicular to the magnetic field then the force would be maximum. The force depends on 1. magnitude of current 2. Magnetic field induction 3. Angle between the direction of current and magnetic field. Fleming's Left hand rule is used to find the direction of force acting on the rod
Which happens to the magnetic field of a wire when you change the direction of the current in the wire?
The polarity of the magnetic field of a wire reverses when you change the direction of the current in the wire.
How does an inducted magnetic field influence the direction of a compass needle?
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.
Which wave cannot exist inside wave guide?
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
What is the effect of a magnetic field on a stationary electric field?
The magnetic field will have no effect on a stationary electric charge. ( this means that the magnetic field is also stationary. ) If the charge is moving , relative to the magnetic field then there might be an effect, but the size and direction of the effect will depend on the direction of the electric charge as it moves through the field. If the charge is moving parallel to the field there will be no effect on it. If the charge is moving at right angles to the field then it will experience a force that is mutually orthogonal to the field and direction of the motion. You really need diagrams to properly explain this
What is the difference in the direction of the magnetic field produced around conductor by dc flow and ac flow?
The direction and amplitude of the magnetic field around a wire depend on the direction and amplitude of the current through the wire. When the wire carries DC, the direction and amplitude of the current in the wire are constant, so the direction and amplitude of the magnetic field around the wire are constant. When the wire carries AC, the direction of the current in the wire is periodically reversing and its amplitude typically changes, so the direction of the magnetic field around the wire is periodically reversing and its amplitude is typically changing.
The force on an electron moving in a magnetic field will be the largest when its direction is?
perpendicular to the magnetic field direction
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.
Which happens to the magnetic field of a wire when you change the direction of the current in the wire The magnetic field?
The magnetic field collapses to zero, then builds up again for the current in the opposite direction.
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.
What is the direction of magnetic filed lines?
The direction of magnetic field lines are from north to south
What is a magnetic field vector?
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.
Why and when does a current carrying conductor kept in a magnetic field experiences a force list factor on which the direction of this force depend State the rule which may be used to determine the di?
Current carrying conductor will have magnetic lines around it. So when it is kept perpendicular to the magnetic field then the force would be maximum. The force depends on 1. magnitude of current 2. Magnetic field induction 3. Angle between the direction of current and magnetic field. Fleming's Left hand rule is used to find the direction of force acting on the rod
Does the magnetic field go from north to south or south to north?
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.
Is magnetic field a scalar or density quantity?
A magnetic field is neither: it is a vector field with both direction and quantity.
Which happens to the magnetic field of a wire when you change the direction of the current in the wire?
The polarity of the magnetic field of a wire reverses when you change the direction of the current in the wire.
