What is done to reduce the magnetic field inhomogeneities when
installing the scanner and before acquiring images? Describe
briefly how these methods work.
What is the difference between the magnetic field of the
bar magnet and
the magnetic field of the solenoid? (also in terms of
how the lines and direction should differ)
what does the H2 vector in this environment when a magnetic
field in the air environment with relative magnetic permeability 1
has a value of H1= 3 ax -4ay +5az and enters the ferromagnetic
environment on the xy plane and has a relative magnetic
permeability 80 ?
pleace type the answer
1.Substances are attracted to magnetic field when they
experience what types of properties?how nare the electrons
paired
2.Spontateity is often diretly associated with the enthaply of a
reaction . Explain how an endothermic reaction can be
spontateous
Find the radius of an electron's orbit when it moves
perpendicular to a magnetic field of 0.46 T with a speed of
6.29×105 m/s .
Express your answer using two significant figures.
1 a) What is the approximate electric field strength and
magnetic field strength of the electromagnetic waves radiated by a
60-W lightbulb, as measured 5.5 m from the bulb? You can assume
that the bulb is 100% efficient in converting electrical energy to
light energy.
b.) Incandescent light bulbs are very inefficient. Find the
electric field strength and magnetic field strength assuming 5%
efficiency.
Please show all work, thank you!
A circular coil of wire consisting of 100 turns, each of radius 8.0 cm carries a current of 0.40 A. What is the magnitude of the magnetic field B at the centre of the coil?
