The invention discloses a character self-falling type electromagnetic writing board, and belongs to the field of writing boards. According to the scheme, electrorheological fluid is turned into a solid state after being electrified, magnetism breaking balls expand, the writing board is separated from magnetism conducting fibers on the outer side of an electromagnetic board, the magnetism, conducted to the surface of the writing board, of the electromagnetic board is reduced, magnetic characters on the surface of the writing board automatically fall off after losing magnetic attraction force, dust generated during wiping is reduced, and a collecting frame is used for collecting the magnetic characters; when writing is conducted on the surface of the writing board, a writing pen has magnetism through a magnet, during writing, the writing pen is fully attracted to the surface of the writing board, magnetic attraction sheets in the writing pen are attracted to the surface of the writing board through magnetism, thermochromic powder at the outer ends of the magnetic attraction sheets change color when heated, the color of characters written on the surface of the writing board is changed according to the change of temperature, and the distinguishing degree of the characters on the surface of the writing board is improved.
Description
technical field [0001] The invention relates to the field of writing boards, in particular to an electromagnetic writing board with self-falling fonts. Background technique [0002] In accordance with laws, regulations and industry norms, and according to school conditions and professional titles, educators educate and cultivate the intellectual development of the educated in a planned and organized manner, and use existing experience and knowledge to teach them to explain various phenomena, Problems or behaviors, in order to improve practical ability, it is fundamentally to treat things with a relatively mature or rational thinking of people, in which people gradually change from sensory touch to cognition and understanding of a thing, and Form a relatively perfect or rational self-conscious thinking, but at the same time, people have self-conscious thinking and their own sensory dimension, so any educational conscious thinking may not be absolutely correct, but should be p...
