containing one of those materials so it an come together. If two magnets align it it is considered to be called a magnetic field. Compasses are used by magnetic fields coming from the North and South Poles. The way magnets come together is magnetic pulls. Examples have you ever tried to push two magnets together? Usually they go to the right or left. That is because there are magnetic fields pushing off of each other. If you just lay them down next to each other they will connect because you are not

following years‚ but it was not until the 1970’s that Japan and Germany showed interest in it and began researching and designing. The motion of the Maglev train is based purely on magnetism and magnetic fields. This magnetic field is produced by using high-powered electromagnets. By using magnetic fields‚ the Maglev train can be levitated above its track‚ or guide way‚ and propelled forward. Wheels and moving parts are eliminated on the Maglev train‚ allowing the Maglev train to essentially move

susceptibility to an external magnetic field. They exhibit a strong attraction to magnetic fields and are able to retain their magnetic properties after the external field has been removed. Ferromagnetic materials have some unpaired electrons so their atoms have a net magnetic moment. They get their strong magnetic properties due to the presence of magnetic domains. In these domains‚ large numbers of atom’s moments (1012 to 1015) are aligned parallel so that the magnetic force within the domain is strong

the years EM came to stand for electromagnetic‚ referring to the way the units actuate‚ but their basic operation has not changed. Electromagnetic clutches come in many forms‚ including tooth‚ multiple disc‚ hysteresis‚ and magnetic particle. However‚ the most widely used version is the singleface design. ABOUT ELECTROMAGNETIC CLUTCH These electromagnetic clutches are designed to have a very high torque to size ratio. They include longlife

MAGNETIC LEVITATION AND TRAINS BY: MANISH KUMAR 2K12/EE/075 Delhi Technological University INTRODUCTION MAGLEV = MAGNETIC + LEVITATION Magnetic means “based on magnets” Levitation means “to rise and float in air” Maglev is a method of propulsion that uses magnetic levitation to propel vehicles with magnets rather than with wheels that the conventional trains use. Magnetic levitation is the use of magnetic fields to levitate a (usually) metallic object. Manipulating magnetic fields and

The displacement measurement was realized by measuring the magnetoelectric output voltage. The displacement detecting coefficient was ~ 2.5 mV/μm at a frequency of ~ 1 kHz. This passive displacement sensor

I designed five different set-ups to test how the magnets react in different ways using these materials. The results of the experiment proved four out of five parts of my hypothesis correct and proved one part of the hypothesis wrong. I learned from my project that the magnetic field can withstand objects in between magnets‚ but the more you put between the magnets‚ the
