A Bit of the History of Magnetism
2000 years ago Humans already know about
natural lodestones 1100s
Chinese used lodestones as a navigational tool
Scientific clothingEarth as magnet

4
So Lets Make the Strongest Magnets in the World
Permanent Magnets 0.4 gauss
Earths Magnetic Field 600 gauss
Iron-Oxide Magnets (refrigerator magnets)
4,000 gauss Neodymium-Iron-Boron (rare earth
magnets)
--- This is near the limit for permanent magnets
15
5
Permanent Magnets Only Get You So Far
Permanent Magnets 0.4 gauss
Earths Magnetic Field 600 gauss
Iron-Oxide Magnets (refrigerator magnets)
4,000 gauss Neodymium-Iron-Boron (rare earth
magnets)
--- This is near the limit for permanent magnets
Electromagnets 450,000 gauss Hybrid
DC Magnet (NHMFL-Tallahassee) 900,000
gauss Pulsed Magnet (NHMFL-Los Alamos)
--- cooling problems (the wire heats up)
(magnets operate for hours) --- ignore the
cooling problem (pulse for less than a
second)

Challenges in Producing Pulsed Magnetic Fields
Pressure Under Water 12 feet
Ears 6 pounds per square inch
2000 feet Submarine
1000 psi 12,000 feet Ocean Floor
6000 psi
Pressure inside NHMFL Pulsed Magnets 800,000
gauss Pulsed Magnet 200,000
psi (which equals 1.4GPa or 130
kg per square millimeter) (which is more
pressure than most materials can handle)

What can you do with 1,400,000,000 Watts ?
You can power Los Angeles
You can go

When we are ready to pulse the magnet... All
personnel evacuate the building The generator
is spun up to 1800 rpm The switch is thrown
The generator spins down in a second The
magnet pulses to 600,000 gauss
and sometimes things go a bit worng

Until You Spread Your Wings, Youll Have No Idea
How Far You Can Walk.

14
So We Also Design, Build and Use World Record
Superconducting Magnets for the REALLY fancy
stuff
Superconducting Magnets for Physics, Chemistry,
and Biology
29
15
We Also Make the Most Powerful DC Magnets in
the World for the more delicate experiments
1999 45T DC Hybrid Magnet (world record)
2003 35T DC Resistive Magnet (world
record)
Resistive and Hybrid Magnets stay turned on for
many hours for Physics, Chemistry, and
Biology Experiments
26
16
We Make the Most Powerful Magnets in the
World without blowing stuff up ...(except
sometimes accidentally)
2009 - 100T Multi-shot Pulsed Magnet
2007 89T Short-Pulse Magnet (shared
world record)
1998 60T Controlled-Pulse Magnet (world
record) (rebuilt in 2008)
Pulsed Magnets stay on for less than one
second pretty much useful only for
Physics Experiments

Oxygen-17 Nuclear Magnetic Resonance
Spectroscopy a new tool for studying biological
membranes
K ion

Our entire nervous system is dependent upon the
proper function of ion channels,
pores in cell
membranes that are able to transport ions, such
as potassium and sodium,
in and out of the cell.
Because 17O is a quadrupolar
nucleus, it is a very sensitive indicator of the
electric fields of nearby ions.
At 21.1 teslas in the 900MHz magnet

we can detect
NMR line shifts due to the electric
fields
of
potassium ions at particular sites

along the
ion channel

Electron Spin Resonance to Probe Organometallics
Iron is important in bio-inorganic chemistry,
appearing in many metallo-proteins (proteins
that function due to the
incorporation of a metallic ion). Despite being
paramagnetic, the Fe(II) oxidation state of
iron is very difficult to detect due to a
very large zero-field splitting (12 cm-1
in the ground spin state). NEED HIGH

Finding Unpaired Electrons in Palladium
A frontier of modern chemistry the
understanding of catalysis on a molecular
level.
Paddle-wheel s ½ complex Pd2 (DAniF)4 PF6
Newly discovered palladium molecules, including
the paddle wheel compound above, might make
better catalysts. Catalysts find extensive
industrial use for their ability to nucleate and
accelerate chemical reactions. Although
X-rays can determine the location of all the
atoms in a molecule, catalysis depends instead on
the location of the electrons, in particular the
location of the unpaired (hence chemically
active) electron. Electron paramagnetic
resonance (EPR), the flipping of an electrons
intrinsic magnetic field, finds that unrequited
electron love for chemical reactions.
Note the increased resolving power of higher
magnetic fields, which requires higher frequency
spectroscopy.
