Why it is an advantage for armature to rotate in radial magnetic field rather than uniform?
1.maximum torque is experienced 2.torque is uniform for all positions of coil
The area around an object that is affected by the magnetism of that object is the?
A Magnetic Force
Does Eris have a magnetic field?
no. Eris does not have a magnetic field
What is a magnetic field made up of?
Magnetic field is made up of magnetic lines.
A current in a long straight wire produces a magnetic field. These magnetic field lines?
The magnetic field lines are arranged circularly around the wire.
Whats meant by radial magnetic field?
A radial magnetic field ensures that the plane of the coil (rotating within the magnetic field, in say a DC motor) is always flat within the external magnetic field ensuring maximum torque in (nearly) all positions. Hope this helps!
Why it is an advantage for armature to rotate in radial magnetic field rather than uniform?
1.maximum torque is experienced 2.torque is uniform for all positions of coil
What type of microwave tube amplifier used an axial magnetic field and radial magnetic field?
That would be a TWT amplifier (traveling wave tube).
What is the importance of radial magnetic field in moving coil galvanometers?
To produce a constant torque on the coil
The area around an object that is affected by the magnetism of that object is the?
A Magnetic Force
Why soft iron is placed in moving coil galvanometer?
1. to intensify the magnetic field by reducing the length of airgap across which the magnetic flux has to pass; 2. to give a radial magnetic flux of uniform density, thereby enabling the scale to be uniformly divided.
Region around a magnet in which magnetic force can act?
Magnetic freild
What is galvanometer magnetic force and motor effect?
A motor effect is when magnetic flux lines interact with the current flow in the current conducting wire (a production of current means there is a production of a magnetic field, thus the magnetic field of a permanent magnet interacts with the magnetic field of the current), hence causing a motor effect, where electric energy is transformed into mechanical energy. In a galvanometer, the concept of the motor effect is used for it to detect and measure the magnitude of small electric currents as an instrument. A galvanometer uses radial magnets which cover more area of the rotor (this is where the needle is attached), as this rotor consists of an armature and loops of wire, it is perpendicular to the magnetic flux lines of the radial magnet. Therefore as the current flows through the coil, a magnetic field is produced, and the motor effect occurs allowing the needle to move on the scale.
How do you write a sentence with the word radial?
The airplane departed the field on a 270 degree radial.
Does Eris have a magnetic field?
no. Eris does not have a magnetic field
What is a region where a magnetic force can be detected?
The magnetic field. If it's an electromagnet, the electromagnetic field.
What is the neutral point of the magnetic field?
In a combined magnetic field, a neutral point is a place where the magnetic field is zero
