Electromagnetic IWB features:1.    High anti-interferenceinteractive whiteboard adopts mature electromagnetic induction technology. Signal induction originals are all inside and non-exposed. It can effectively resist the interference of the light in the external environment and the dust in the classroom.2.Precise orientation and sensitive reactionElectromagnetic induction technology is also called “Electromagnetic Matrix Positioning Technology”. Within the whiteboard, it is full of electromagnetic induction coils. It is orientated through the interaction between the signal sent by Electronic Pen and the induction coils. Due to the short contact distance, it can be orientated precisely. Without the Location deviation made by Location Technology of long distance, The whiteboard with Electromagnetic Induction Technology can maintain the handwriting fluent and smooth .3.Excellent abrasion resistance and high strength structure interactive whiteboard adopts Polymer Material of high strength and exceptional wear resistance . It can last for long time. The frame is made of alloy material .It has high strength structure and hard to distort.
