The present disclosure discloses an information input method, device and electronic apparatus and belongs to the technical field of touch control. The method includes displaying a predetermined sliding track and a slider located on the predetermined sliding track, the predetermined sliding track including at least one candidate stop-node, each candidate stop-node being corresponding to a piece of candidate input information; receiving a control signal corresponding to the slider; causing the slider to change a position on the predetermined sliding track according to the control signal; and, taking the candidate input information corresponding to the candidate stop-node where the slider stays as input information when the changed position of the slider is one of the candidate stop-nodes. The present disclosure solves the problem of relatively low input efficiency in the existing information input method.

A method for reducing eddy currents caused by the gradient magnetic field in a magnetic resonance system employs an anti-eddy current device formed by a number of laminated metallic plates, and includes the steps of calculating the distribution of the main magnetic field of the magnetic resonance system in the anti-eddy current device, calculating the distribution of the main magnetic field and the gradient magnetic field in the anti-eddy current device, subtracting the calculated distribution of the main magnetic field in the anti-eddy current device from the calculated distribution of the main magnetic field and the gradient magnetic field in the anti-eddy current device, to obtain the distribution of the gradient magnetic field in the anti-eddy current device, and adjusting the setting of the metallic plates of the anti-eddy current device based on the distribution of the gradient magnetic field in the anti-eddy current device, so as to reduce the eddy current. The adjustment in the metallic plates of the anti-eddy current device should be such that the gradient magnetic field is parallel to or substantially parallel to the plane of the metallic plates. The metallic plates can be further divided into a number of areas, or the laminating direction of the metallic plates in different areas can be adjusted according to the specific distribution of the gradient magnetic field to obtain the optimum effect of eddy current reduction.

The invention proposes a method and an apparatus for testing a magnetic field of a coil. The method comprises applying an alternating current to the coil to generate an alternating magnetic field; measuring simultaneously the induced electromotive potential at a plurality of positions in the alternating magnetic field; and collecting and processing signals of the induced electromotive potential so as to obtain said coil's magnetic field distribution. The apparatus comprises probes positioned in said alternating magnetic field to generate the induced electromotive potential; a multi-channel data acquisition card for collecting the signals of the potential; and a processor for processing the collected signals to obtain said coil's magnetic field distribution. The method and the apparatus eliminate the interference by the magnetic field of the earth by testing the coil's alternating magnetic field to improve test accuracy and to improve the testing efficiency by multi-channel acquisition of the test signals.
