Embodiment Construction

[0039] The preferred solution is as Figure 1 to Figure 3 As shown, a ferrofluid hourglass experimental device and its time adjustment method with adjustable aging include an hourglass body 1, an electromagnet coil 8 is arranged at the upper and lower ends of the hourglass body 1, and a magnetic fluid 3 is housed in the hourglass body 1. The main body 1 is connected with the control box 2, and a control circuit is arranged in the control box 2, and the control circuit includes a power supply 5, and the power supply 5 is connected in series with a resistance regulator, a power switch and an electromagnet coil 8. The control box 2 can be arbitrarily selected to be installed on the upper end or the lower end of the hourglass body 1 . The hourglass body 1 is made of high-transparency acrylic material, which is conducive to the passage of magnetic force lines and more accurate measurement. This technical solution adjusts the size of the control loop current by adjusting the resist...

Abstract

The invention discloses a magnetofluid hourglass experiment device capable of regulating and controlling aging and a time regulating method thereof. The device comprises a sandglass body, electromagnet coils are arranged at the upper end and the lower end of the sandglass body respectively, magnetofluid is contained in the sandglass body, the sandglass body is connected with a control box, a control circuit is arranged in the control box, and the control circuit comprises a power source which is connected with a resistance regulator, a power switch and the electromagnet coils in series. The resistance value of the resistance regulator is regulated, so that the current of the control loop is regulated, the current can influence the intensity of a magnetic field generated by the electromagnet coils, the magnetic field intensity can influence the falling time of the magnetofluid, and the time adjustability of the magnetofluid hourglass experiment device is completed.

Description

technical field [0001] The invention belongs to the field of hourglasses, and in particular relates to a time-adjustable magnetic fluid hourglass experimental device and a time adjustment method thereof. Background technique [0002] The problem with ordinary hourglasses is that the metering time is fixed and the length of time cannot be adjusted. Chinese patent document CN 209118083 U records a kind of "hourglass with adjustable timing time", which adopts a mechanical structure to adjust the time of sand blanking, and this method is inaccurate in adjusting the time. [0003] Magnetic fluid is a new type of functional material, which has both the fluidity of liquid and the magnetism of solid magnetic materials. It is a stable colloidal liquid formed by mixing magnetic solid particles with a diameter of nanometer scale (below 10 nanometers), base carrier liquid and surfactant. The fluid has no magnetic attraction when it is static, and it shows magnetism when an external ma...
