The force on an electron moving in a magnetic field will be the largest when its direction is?
perpendicular to the magnetic field direction
What effect does a magnetic field have on a charged particle?
Yes, a moving electron will create a magnetic field. Any moving charge will create a magnetic field around its path of travel. This is the basis for the electromagnetic force, which is one of the four fundamental forces in nature.
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
How can the direction of magnetic field lines at a place can be determined?
Get a magnet that's free to turn in any direction ... a boy-scout compass will do nicely.Place it in the magnetic field. It rotates to point in the direction of the field 'lines' atthat location. (I forget whether it's the north or south pole of the compass that pointsin the direction of the magnetic field, or opposite to it.)If you like, move your detector slowly, always following the direction in which it points,and you'll trace out a complete 'line' of the magnetic field.
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.
What effect does a magnetic field have on a charged particle?
Yes, a moving electron will create a magnetic field. Any moving charge will create a magnetic field around its path of travel. This is the basis for the electromagnetic force, which is one of the four fundamental forces in nature.
Why the oscillations of a copper disc in a magnetic field are lightly damped?
Lenz's law: Induced current is always antiparallel to the motion that's causing it. As a copper disk goes through a magnetic field in one direction, the magnetic field induces a current on the disc which is in such a direction as to create an electric field on the disc in the direction opposite its motion. Reeks of Newton doesn't it? The electric force is therefore always slowing the disc down, otherwise known as damping.
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.
