You forgot to add required="" and aria-required="true" here is the completes snippet:

<div class="row">
    <form class="col s12">
        <div class="row">
            <div class="input-field col s12">
                <input id="email2" type="email" class="validate" required="" aria-required="true">
                <label for="email2" data-error="wrong" data-success="right">Email</label>
            </div>
            <div class="input-field col s12">
                <input id="example" name="example" type="text" class="validate" required="" aria-required="true">
                <label for="example" data-error="wrong" data-success="right">Field</label>
            </div>
            <div class="input-field col s12">
                <button class="btn waves-effect waves-light" type="submit" name="action">Submit</button>
            </div>
        </div>
