If the magnetic flux is zero, the magnetic field must also be zero True False
Part A If the electric flux through a closed surface is zero, the electric field at points on that surface must be zero. True False Submit Request Answer
15. Magnetic flux can be described as the number of magnetic field Lines passing through a surface. True False
Moving charges will produce a local magnetic field, but the reverse is also true a changing magnetic field will similarly induce charges to move (ie. produce current). Consider a magnet moving into a coil of wire: A spinal coil of wire with many closely-spaced tums this is called a solenoid is connected to a micro-ammeter as shown in the diagram above. As the magnet moves into the coil, any induced current will be measured by the micro-ammeter. Question On the...

a) Explain how magnetic flux can be zero when the magnetic field is not zer. b) A person who works with large magnets sometimes places her head inside a strong fie ld. She reports feeling dizzy as she quickly turns her head. How might this be associated with induction?
Which of the following statements are equivalent to saying that the flux of the magnetic field through any closed surface is always zero? (select all that apply) there are no magnetic monopoles in nature magnetism obeys Faraday's Law magnetic field lines are always closed loops magnetic field lines can never cross the induced emf always opposes the change in the flux magnetic field lines are basically the same as electric field lines
A flux meter is a device that measures the magnetic field strength. The flux meter has a conduction coil of 1700 turns with the area of the coil as 5.10 X 10-4 m2 . The coils are connected to a galvanometer and has a total resistance of 55.0 ohms. The coil is moved from a region where the magnetic field is zero into a region where it is nonzero, the normal coil to the coil being kept parallel to the...
True or false _____ the strength of the earth’s magnetic field at the surface of the earth is about 1 Gauss ______ The north and south poles of the earth switch periodically _______ the earths magnetic field is distorted by solar wind _____ the earth’s magnetic field helps to create the Northern and Southern Lights _____ the earth’s magnetic field in space is called the magnetosphere.
A positive charge traveling along a magnetic field experiences no magnetic force (True,False)
A moving charge or current can produce a magnetic field. True False
