Superconductors & Electromagnets

Superconductors allow electricity to flow with no resistance below a certain temperature, enabling powerful magnets. Electromagnets are coils that become magnetized when electricity flows through them, allowing control of magnetic fields for lifting loads or attracting parts. Tesla coils transform electricity into high voltage, high frequency currents to conduct experiments on wireless power transmission and more.

metals, alloys, and
ceramics is essentially
zero at certain low
temperatures
• Superconductivity was created by
H.Kamerlingh Onnes in 1911
• Magnetic Resonance Imaging
• Medical Studies of human heart, brain, and
other physical science experiments
• A completely superconducting prototype
computer
• High-powered magnets in medical imaging
machines and particle accelerators
• Small energy loses
• more cost and power efficient
• able to carry large currents for
long periods of time with small
energy loses at heat
• have carried currents for years
with no recordable loses
• There is a restricted range for operating
temperature
• not a practical room temperature device
• would have to be cooled with liquid Nitrogen
• sensitive to a changing magnetic field
• AC current does not work effectively with
superconductors
*A magnet consisting
essentially of a coil of
insulated wire wrapped
around a soft iron core that is
magnetized only when
currents flow through the wire
• William Sturgeon created the first
electromagnet in 1825
• To lift heavy masses of magnetic
material

• To attract movable magnetic parts


of electric devices

• In common electrical systems


• Can carry much higher loads than
permanent magnets
• Strength is readily controllable

• Can be made to work with loads of
temperatures up to 600 degrees
Centigrade
• Not water resistant or shock resistant or
heat resistant

• Power failure can cause damage/injures

• Eventual burnout
• It is a form of transportation that
suspends, guides, and propels vehicles
using the electromagnetic force

• It’s highest speed was 361 miles per


hour
• A Telsa coil
is a
transformer(a
device used
to transform
electric
energy) with
an air core
• Nikola Tesla
created the
Tesla Coil in
1891
