Electromagnetic pen with multifunctional tail end

The invention relates to an electromagnetic pen with a multifunctional tail end, which comprises a pen body, a pen nib and a multifunctional electromagnetic coil, wherein the pen nib and the multifunctional electromagnetic coil are respectively arranged at the front end and tail end of the pen body; the multifunctional electromagnetic coil can emit the electromagnetic signals with different frequencies; and the electromagnetic signals with different frequencies are defined by a digiboard to represent different functions, such as erasure, amplification, oil painting knife and the like. A user can control and change the frequencies of the electromagnetic signals which are emitted by the multifunctional electromagnetic coil through the switch which is arranged at the side of the pen body, thereby enabling the multifunctional electromagnetic coil to change the functions of the multifunctional electromagnetic coil. Thus, the tail end of the electromagnetic pen provided by the invention does not need to be in contact with the digiboard and can start the functions of the electromagnetic pen; the electromagnetic pen can directly move at the upper part of the digiboard to execute the operation of the electromagnetic pen; and the electromagnetic pen cannot generate abrasion because of the friction with the digiboard.
