What Will Adding An Iron Core To The Inside Of The Electromagnet Do To The Magnet? Putting a piece of iron or steel inside the coil makes the magnet strong enough to attract objects. The strength of an electromagnet can be increased by increasing the number of loops of wire around the iron core and
What Are The Source Of Electric Field And Magnetic Fields? The electric field is produced by stationary charges, and the magnetic field by moving charges (currents); these two are often described as the sources of the field. The way in which charges and currents interact with the electromagnetic field is described by Maxwell’s equations and
What Happens When A Magnet Is Placed Near A Copper Wire? Magnetism and electricity are closely related. When a magnet moves near copper (or other metals) it sets up electrical eddy currents. The eddy currents will repel the magnet as it falls down the copper tube. This repulsion pushes against the magnet and slows it
