Bonded Magnets: A Versatile Class of Permanent Magnets
By Dr. John Ormerod, Senior Technology Advisor | Magnet Applications, Inc., A Bunting Magnetics Company
Permanent magnets are ubiquitous in modern societies. Devices that use permanent magnets include motors, sensors, actuators and acoustic transducers. These are used in home appliances, speakers, office automation equipment, aerospace, wind turbine generators, medical laboratory diagnostic test equipment and more. It is estimated, for example, that a typical automobile uses up to 120 permanent magnets in windshield wipers, starter motors, seat adjusters, door lock actuators, fuel pumps, sensors and gauges. The development of hybrid electric vehicle and electric vehicle drive technologies has been greatly enhanced by the availability of high performance magnetic materials. <read more>

Tips for Choosing a Hall Probe for Your Application
Choosing the right Hall probe for your Hall effect gaussmeter application is a crucial decision. Using the improper probe could lead to less than optimal accuracy or, even worse, costly damage. Lake Shore probes are factory calibrated for accuracy and interchangeability. Our experts can recommend or custom design a probe that will ensure the greatest accuracy for your application.

Some tips for choosing a Hall probe include:

• Do not select a probe with more accuracy, field range, or fragility than is actually needed.

• The thinner a probe, the more fragile it is. Don’t choose an easily damaged probe based on a possible, but not required, future application.

• Choose a metal-enclosed probe or brass transverse probe when practical; these offer protection to the Hall sensor.

• For AC magnetic field measurements, a probe with a stem made of fiberglass epoxy material will generally ensure the greatest accuracy. 

• Probe stem length is typically chosen based on user preference or test set-up dimensions. Stem length does not affect performance. 

• When measuring magnetic fields with a high gradient across the sensor width, select a probe with the smallest active area practical.

• See our Hall probe selection guide to learn more.

Lake Shore Hall probes are compatible with our versatile benchtop and handheld Hall effect gaussmeters, which allow for both AC and DC magnetic field measurement in a variety of research and industrial applications.

Articles Needed for MB&T's Winter / Resource Guide Issue

Magnetics Business & Technology magazine is looking for contributed articles, application profiles, case studies and white papers for our Winter 2015 / Resource Guide Issue. We are seeking industry experts to contribute articles on Magnetic Applications for Renewable Energy.  We are also looking for Technical articles on EMI/EMC and Medical Applications.  The articles should be technology- or application-based, and not product-based. If your company is interested in getting featured in our next issue, please pick one of these topics and submit a short abstract outlining what the article would cover, the title and the author. 

The deadline for article abstracts is Wednesday, July 24th.
