• state lenz law of emi
  
• solve my doubt
  
• The value of magenetic field produced by coduction current and displacement current are equal at the edges ofor capacitor or not?
• Suppose this page is perpendicular to a uniform magnetic field and the magnetic flux through it is 5 wb. If the page is turned by 30 degrees around an edge the flux through it will be: 1. 5.0 wb 2. 4.3 wb 3. 10.0 wb 4. 2.5 wb 5. 5.8 wb
• Why displacement current is induced in a coil by change in magnetic flux produced by another coil in vicinity?
• What is magnetic flux?
• Write an expression for the magnetic flux linked with the surface?
• What is the units of magnetic flux? How are they related? Is magnetic flux a scalar or vector quantity?
• A coil of area 0.5 m² is situated in a uniform field B = 2 Wb/m² and the normal to the plane of the coil makes an angle of 60° with respect to the magnetic field. Find the magnetic flux through the area A.
• A circular coil and a bar magnet placed nearby are made to move in the same direction. If the coil covers a distance of 2 m in 1 sec and the magnet a distance of 4 m in 2 sec. calculate the induced emf produced in the coil.
