Magnetic Fields And Electric Currents, Part 1

Beginning with a discussion of the simple magnetic properties of iron materials, the film uses models to demonstrate the existence of a magnetic field in the vicinity of a current-carrying conductor. Properties of the magnetic field, such as direction and strength are established by experimentation., Uses simple magnets and compasses to demonstrate the existence and characteristics of the magnetic field surrounding a direct electrical current. Shows induced magnetism in previously unmagnetized materials and demonstrates their common properties with all other magnets. Introduces, through experimentation, the right hand rule for determining the direction of the magnetic field., Explores the magnetic properties associated with a wire carrying a direct electric current.NOTE: Two (or more) records have been merged together to create this data.
