Can a magnet passing thru a coil of wire transfer it's kinetic energy to the coil of wire as kinetic energy if the coil of wire is not secured?

If a magnet is passed through a coil of wires, it will produce a current in the coil of wires. If the coil of wire is not secured when the magnet passes thru the coil of wire can it transfer other than electrical energy to the coils? Can it also pass on some kinetic energy?  Thus moving the coil in the same direction of the traveling magnet.

Kinetic energy is the energy of motion.  You are describing two different types of energy here, one being kinetic energy, the other being electrostatic energy by induction.  Kinetic energy is caused by something with mass moving at a specific velocity, such as the magnet falling, passing through the coil of wire.  The only way the magnet can transfer some of that kinetic energy is to make contact with the coil of wire.  If it "bumps" into one or more coils of wire, then yes, some of the kinetic energy will indeed be transferred to the coils of wire.  If the magnet continues its downward progression through the coil of wire, the magnetic field will induce a flow of electricity through the coils of wire, which is known as electrostatic induction.  This is the principal behind van de Graaf generators. to pass a magnetic field through a coil of wire and create a flow of electricity flowing through coils of conducting electrical wire.
