A randomized, double‑blind experiment studied whether magnetic
fields applied over a painful area can reduce pain intensity. The
subjects were 5050 volunteers with postpolio syndrome who reported
muscular or arthritic pain. The pain level when pressing a painful
area was graded subjectively on a scale from 00 to 1010 ; (where 00
is no pain, 1010 is maximum pain.)
Patients were randomly assigned to wear either a magnetic device
or a placebo device over the painful area for 4545 minutes....

(Practical magnetism) As we will see in lab, the magnitude ?? of
the magnetic field of a permanent magnet drops with distance d so
that ?? ∝ 1/? 2 when d is less than the size of the magnet (where
you “feel” only the closest pole) but ?? ∝ 1/? 3 farther away
(where both poles “blur together” and the field is weaker). (a)
Could a coin-sized magnet in your wallet or purse erase the

1. Chromium, Cr, has 24 electrons. Write out the entire electron
configuration for chromium using spdf notation.
2. How many unpaired electrons would you expect for chromium in
[Cr(H2O)6] 3+? Is this a paramagnetic or diamagnetic material?
3. Cobalt, Co, has 27 electrons. Write out the entire electron
configuration for cobalt using spdf notation.
4. How many unpaired electrons would you expect for manganese...

If the radius of the coils is 50 cm, what would be the (peak)
magnetic field at the center of a single coil
loop? (Show work.)
Use the concept of electromagnetic induction to explain why the
light bulbs in the chandelier light up. Recall that they
are in the presence of a strong, rapidly changing magnetic field!.
The chandelier is not plugged in, so presumably the filaments in
the light bulb are not part of any closed circuit. Yet
there appears to be...

scanner. Include a figure and some of the design considerations
required for each component.

Helmholtz coils are a method developed to provide a uniform
magnetic field in a small region. They are constructed by placing
two identical wire loops parallel to each other, separated by a
distance equal to their radii, as shown in the Figure. Assume that
the two loops are also connected in parallel to a power supply, so
that they produce the same field.

75 Ω coil.

A proton travels through uniform magnetic and electric fields.
The magnetic field is in the negative x direction and has a
magnitude of 3.52 mT. At one instant the velocity of the proton is
in the positive y direction and has a magnitude of 2600 m/s. At
that instant, what is the magnitude of the net force acting on the
proton if the electric field is (a) in the positive z direction and
has a magnitude of 5.40 V/m, (b)...

A proton travels through uniform magnetic and electric fields.
The magnetic field is in the negative x direction and has
a magnitude of 3.50 mT. At one instant the velocity of the proton
is in the positive y direction and has a magnitude of 1830
m/s. At that instant, what is the magnitude of the net force acting
on the proton if the electric field is (a) in the
positive z direction and has a magnitude of 5.10 V/m,
(b)...
