A loop of wire is placed within a magnetic field If the loop of wire is stationary as is the magnetic field will a current be induced in the wire?

No it will not. In order to get electrical activity you need motion. Either the magnet or the wire must move.

What is the Hall effect?
If a semiconductor carrying a current ( I ) is placed in a transverse magnetic field ( B ), an electric field ( E ) is induced in the direction perpendicular to both I & B.This is called hall effect.for full explanation visit http://www.ecematerials.com/2013/07/hall-effect.html
When does current carrying conductor placed in a magnetic field experiences a maximum force?
It experiences maximum force when it is placed perpendicular to the direction of magnetic field.
What is definition of paramagnetic and dimagnetic materials?
A dimagnetic material produces a magnetic field that opposes an external field. A paramagnetic materia, on the other hand, produces a magnetic field that increases an external field. Dimagnetism and paramagnetism are induced when an object is placed in a magnetic field.
When a compass is placed near a conductor where current flows its needle would deflect what does this indicate?
This proves that a magnetic field is developed around the conductor wen current flows through it...
Does a magnetic fIEld have an effect on a capacitor placed in between the plates?
Does a magnetic field have an effect on a capacitor when it is placed between the plates? Yes, a magnetic field between the plates of a capacitor would have some effect. Without more information it is difficult to determine how much.
What happens When a wire with a current is placed in a magnetic field?
electricity is induced
Why is magnetism induced into an iron bar placed near a magnet?
A magnetic field induces an electric current. Hence, by placing the iron bar close to the magnet, a current is induced; and so we are, in effect, creating an electromagnet.
When a wire with a current is placed in a magnetic field what happens?
The wire magnetics will make move attract or repulse see speakers
How does an water make an electrical generator work?
When a conductor of electricity moves through a stationary magnetic field, an electric current is induced in the conductor. A hydroelectric generator uses flowing water to spin an axle that is wrapped in conductive wires in a strong magnetic field. Current is generated in the wires, and that current is directed into the electrical grid. The actual process is somewhat more complex but that's the basics. The inverse is also true - when a stationary conductor is placed in a changing magnetic field, current is generated in the conductor. This is how an antenna works - radio waves generate a changing magnetic field which creates electrical current in the conductive antenna which is directed into the electronics in the radio where it is amplified so you can hear it.
Why is current produced in a coil if it is placed near other coil containg electricity?
When the current in a nearby coil changes, the magnetic flux associated with it changes and an induced emf is produced in the other coil.Hence, induced current is produced.
If a conductor placed in electric field is there any emf induced in the conductor?
one condition for the above question is either conductor or magnetic field must be rotating.considering rotating field and stationary conductor,the magnetic flux will be cut up by conductor resulting in the induced emf in the conductor.
What happens when a compass is placed near a current-carrying wire?
That depends. If we assume that current is flowing though the wire then there is an induced magnetic field equal to B=u_o*I/(2R*pi). For a visual refer to http://hyperphysics.phy-astr.gsu.edu/HBASE/magnetic/magcur.html#c2
When an aluminium ring and a solenoid is placed together why as current increases in the coil the ring repels?
The Solenoid is an electromagnet. The aluminum ring is a conductor that will have a current induced in it by the Solenoid's changing magnetic field. The current in the Aluminum ring will generate a magnetic field of the opposite Polarityof the Solenoid. Therefore they repel one another.
When is the force experienced by current carrying conductor placed in a magnetic field strongest?
The force experienced by a current carrying conductor placed in a magnetic field is strongest when that conductor is placed perpendicularly to the magnetic field.
Why is brushes placed at MNA in a dc generator?
to avoid sparking ,since their is no e.m.f induced in magnetic neutral axis.
