A loop of wire forms a right with legs of length 3m and 4m. The loop is placed in a magnetic field of 5 T at a 45° to the magnetic field. What is the magnetic flux through the loop?（ ）
What is an ideal liquid? What is the "flux" (number of lines) flowing through the left side of the shape? What about the slanted right hand side? What is electric flux in physics? Define the viscosity. What is the unit of magnetic flux?
"number of lines." It makes a certain kind of sense - the more flux lines you have going through some area, the more magnetic flux you have. This unit of measurement really isn't used anymore, but sometimes the nomenclature sticks around. We get asked, "How many lines of flux is in...
What is motional emf explain it with derivation? the magnetic flux ϕB enclosed by the loop PQRS. ϕB=Blx. As x is changing with time, the rate of change of flux ϕB will induce an emf given according to Faraday's law of electromagnetic induction :ϵ=−dtdϕB...
What is a nominal current? What is a turbidity current? What are air currents? Toward which direction does a NW wind blow? What is magnetic flux? What is the unit of electric flux? What direction is lateral? What is the South Equatorial Current?
But the current in the solenoid isolenoid creates the magnetic field inside the solenoid which in turn creates the magnetic flux ΦB through the loop. So we are justified in saying that the induced emf is due to a changing magnetic flu...
The law says that the magnetic field induced by the current, when integrated along the closed loop C is proportional to the current enclosed by the loop. Maxwell understood that the Ampere's Law does not apply to all situations and saw the need for another term - called the displacement ...
As magnetizing force is decreased to 0, the core material does not demagnetize at the same rate. At point b with 0 Oe magnetizing force applied, the flux density is still about +12,000 G. At this point, the current through the coil is reversed so that the core magnetizes in the ...
Let us take an imaginary loop around the conductor. We also call this loop as amperian loop. Let us also imagine the radius of the loop is r and the flux density created at any point on the loop due tocurrentthrough the conductor is B. ...
