FIELD: The area around a magnet where another magnet would feel a force. MAGNETIC FIELD LINES: Show the direction of the magnetic field. The lines run from North to South. Where the field is strong‚ they are close together. INDUCED MAGNETISM: A magnetic material can be magnetised by being placed in a magnetic field. ELECTROMAGNET: A current-carrying coil of wire (SOLENOID) often wrapped around a soft magnetic core which produces a magnetic field quite like a bar magnet with uniform field lines

could be separated with a magnet. My flow sheet was pretty accurate. We started by separating the iron‚ which was by far the coolest part‚ watching the magnet pull up every tiny filing of iron out of the mixture was awesome. Getting that iron onto the scale and off of the magnet was the hard part though. I removed the plastic‚ which I had wrapped around the magnet‚ but when I removed the plastic the iron filings simply left the plastic and continued to cling to the magnet‚ so I had to scrape them

involved. Many hospitals are seeking Magnet status. One of the requirements for a hospital to apply for Magnet status is for 80% of the nursing staff to be Bachelors prepared. A hospital receives many benefits with magnet status; nursing quality care‚ patient results‚ patient safety‚ improved work environment‚ improved nurse satisfaction‚ and nurse recruitment and retention. A magnet hospital is a status representing a quality hospital. Much of the work implemented in magnet hospitals is completed and implemented

electrical current flowed freely through it. In 1933‚ the “Meissner effect” was discovered. It told of a magnet moving by a conductor by electrical currents in a conductor. This effect is the basis for conventional generators. However‚ superconductors the magnet is repulsed. The current is mirrored through the field that would have been penetrated. This is called magnetism and causes magnet to be levitated above superconductor material. In 1989‚ the Illinois Superconductor was the first to commercialize

lab doesn’t have multiple experiments for us to test this but I would hypothesize that the two variables would have a positive correlation: higher voltage‚ faster spin. I built my tiny motor out of magnet wire‚ a magnet‚ two paper clips‚ a 1.5 V battery‚ and two push pins. I curled the magnet wire around the battery so that it was in a coil shape‚ then pulled the ends out so that it had tails. Then‚ I used sandpaper to manipulate the clear coating on the ends of the magnetic wire. The paperclips

stepper motor uses the theory of operation for magnets to make the motor shaft turn a precise distance when a pulse of electricity is provided. You learned previously that like poles of a magnet repel and unlike poles attract. Figure 1 shows a typical cross-sectional view of the rotor and stator of a stepper motor. From this diagram you can see that the stator (stationary winding) has eight poles‚ and the rotor has six poles (three complete magnets). The rotor will require 24 pulses of electricity

teaching might be. Many different extraordinary educators have created what they believe to be the best method of teaching. Some of those methods include Waldorf‚ Montessori‚ and Sudbury education systems‚ as well as the education system known today as Magnet schools. These types of schools offer an overwhelming different education to the traditional public schools of today. Although these schools can be a costly alternative‚ the reward at completion is immeasurable. These students have shown to move through

Explain what it means when we say a substance is magnetic. A substance can be picked up by a magnet. Discuss the relationship between electric and magnetic fields. The magnetic field will be perpendicular to the electric field and vice versa Before you begin your lab‚ you need to form a hypothesis that reflects which material‚ voltage‚ and number of winds you think will produce the strongest electromagnet. Record your hypothesis as an if then statement. If I use copper‚ 100 volts‚ large thickness
